Today we’ll talk about a problem that users often encounter when installing computer games or programs. At the beginning of the article, we’ll tell you why the problem appears, and then we’ll figure out how to deal with it. Unarc.dll returned error code 12 - this window often appears when installing repacks, patches and modifications.

RePack this is a repackaged, archived toy, software, program

unarc dll error code 12

Many people seeing the warning “An error occurred during unpacking: The archive is damaged!” They think that they downloaded a broken version, a damaged file, an archive. This is not always the case and depends on the specific code in the information window. On computers with Windows XP, Windows 7, 8, 8.1, the warning occurs more often than in the 10th version of the operating system, since its appearance partially depends on the programs installed on the system for working with packed archives.

Look at the screenshot above and the returned code in the field, they are different, as are the reasons for the appearance:

Compare with your message, if the code is exactly 12 or 1, then the file may be broken, not downloaded completely, or the connection to the network or server may have been lost. In this case, it is recommended to download the distribution again. If the problem persists, find another resource. Code 7 or another with the message decompression fails means that the archive is ok. All that remains is to finish reading the article and start the installation process.

How to fix unarc.dll and isdone.dll error

Files with .dll extensions are system libraries. Problems in the registry, incorrect files and their absence cause the described troubles with different codes. There are many types of codes, so we immediately use universal solutions. First of all, we strongly recommend downloading and installing the wonderful DLL-Files Fixer program.

This is a universal tool for fixing errors related to libraries and missing DLL components. To avoid the hassle of installing each component separately, we will use special software.
On the developers' website you can find a trial version - DLL-Files Fixer. Bad boys and girls can open Google and download the version with the key.
After installing DLL Files Fixer, open the "Install DLL Files" tab. Enter the name in the search field, then the program will search and install the file. In our case, we need two libraries unarc.dll and isdone.dll; after installing them, the errors should disappear. We launch the installation of the game, program, and check.
In addition, this utility works great with the registry - it cleans and corrects errors. Before any manipulations with the registry, be careful and careful - immediately save a backup copy.

We install an archiver to solve problems with unpacking.

When creating repacks and their modifications, different compression methods are often used. It’s good if users have at least the updated Winrar. However, it’s even better to set yourself 7-zip archiver - it works with additional and well-known compression algorithms, is compatible with all versions of Windows 10,8,7,Vista, XP, has its own 7z format and is completely free. You can download it from the link above from the developers’ website. These manipulations will help most users solve the problem.

A few more points for those facing this problem

• 1. It is necessary to increase the paging file. It will only help when installing heavy games larger than 10 gigabytes. Usually it is set equal to the size of RAM.
• 2. Name the folders in which you are going to install the application Latin letters: Games, Soft, Programs. It is not always pleasant for the operating system to work with Cyrillic, these are rather relics of the past, but on older systems such as Windows XP it can work.
• 3. Problems with RAM and hardware.

Inspect the RAM boards for integrity. It helped many people to carefully wipe the contacts of the dies with an eraser and put them in place. You can clean the memory slots with a soft brush; many people recommend switching to dual-channel operating mode.
If the slots are not working, place the die in another compartment (if you have more than one or two slots), try turning off the strips one by one.

Standard Windows 7 tools and utilities are not always able to identify faults in hardware and RAM, so sometimes you have to manually go through the options.

I hope you figured out what unarc dll error code is 12,1,7 and others. Here is another way to solve the problem proposed on the YouTube channel:

Sometimes Code 1 blue screen errors related to hardware can be caused by corrupted random access memory (RAM). If you are experiencing random computer reboots, beeping sounds on startup, or other computer problems (in addition to BSOD 1 errors), then it is highly likely that your memory is corrupted. In fact, almost 10% of application crashes on Windows OS are caused by memory corruption.

If you have recently added new memory to your computer, we recommend temporarily removing it to make sure it is not the cause of the Code 1 error. If this action clears the BSOD, then that is the source of the problem, and therefore the new memory is either incompatible with some other device. either your equipment or is damaged. In this case, you will need to replace new memory modules.

If you did not add new memory, the next step is to run a diagnostic test on your computer's existing memory. A memory test will scan for severe memory failures and intermittent errors that could be causing your Blue Screen of Death 1.

Although recent versions of Windows include a RAM test utility, I highly recommend using Memtest86 instead. Memtest86 is a BIOS-based testing software, unlike other test programs that run on Windows. The advantage of this approach is that the utility allows you to check ALL operating memory for Code 1 errors, while other programs cannot check memory areas occupied by the program itself, the operating system and other running programs.

Avid gamers in our country very often have to face various problems when installing games. One of the problems is pop-up windows in the form of: "Unarc.dll returned error code: 11" or other code values ​​1, 5, 6, 7, 8. In general, the number does not make much difference. All these types of conflicts are eliminated by the same solutions. Next we will show you how to fix error code -11 when installing games.

Failure to install games "Error code: -11"

What is this error code -11?

The first thing you should always pay attention to is downloaded file. Most likely, it is not licensed, which means it may contain a bunch of problems. Exactly "pirate" games become to blame for the impossibility of their installation. Extracting software from a downloaded archive comes with many risks, because the possibility of not completing the operation always remains. The same rule applies to torrent downloading itself.

Solution to "error code -11" in games

First, analyze the process of downloading the game onto your computer. Perhaps at some point the Internet connection failed and the file was not downloaded or the integrity of the file was compromised. In another situation myself the game was already broken(pirated version) or damaged during analysis by your antivirus.

1. The solution is to re-download the file, but first disable your antivirus.
2. Find an alternative to this software. Please refer to earlier versions or other download sources.

I think everything is simple here. It is the downloaded file in 90% cases is the fault.

Trying to unpack the archive

It is highly recommended that all users have several archivers on their PC. This is due to the fact that sometimes a particular archive cannot be opened, which is why the user may receive a notification "error unpacking unarc.dll". For such situations, it is better to try several archivers.

1. Install two or three archivers with the best features at once: WinRar, WinZip, 7-Z.
2. Try to open each of them one by one.

Sometimes this method helps players unpack games.

Russian letters on the way

Russian letters or Cyrillic Always conflicts with many utilities. Foreign programs cannot recognize such characters in their installation path. These strange characters are the cause of “returned error code: -11”. Although modern developments have almost eradicated this situation, the user still falls into such cases.

• Correct the name of the folder where you are going to install the game. For example, if the folder is called GTA 5 Online, then change to GTA 5 ONLINE.

In general, make it a habit to always write folder names on your computer in English.

Check out our material on solving a similar problem with.

Hard drive is full

Modern games are very impressive in size. At least remember the most popular series GTA 5. It will take up at least 65 GB of hard drive space. This situation is sometimes missed by users with weak PCs. As a result, it turns out that there is simply no free space. When you try to unpack a large archive, “error code No. 1,2,3, etc.” will appear.

Error ISDone.dll usually occurs during the installation of games on Windows 10 and its predecessors. The main reason for this problem is that there is not enough memory to process the application, or the DLL files are missing or damaged. Large PC games often fall victim to this problem due to lack of free RAM space. Therefore, to fix ISDone.dll error in Windows 10, you need to focus on two areas: 1. Memory, 2. DLL files. There are 2 possible situations in the RAM, it is too small to run the game or damaged during crashes. On the other hand, if a dll file is the cause, then a damaged or missing file is the reason you should focus on. In most cases, the ISDone.dll error occurs due to a faulty file Unarc.dll located in the System32 folder on 32-bit operating systems and the SysWOW64 folder on 64-bit systems and produces the following error message:

An error occurred during unpacking: The archive is damaged! Unarc.dll returned error code - 1, 11, 12, 7...

Therefore, if you see this error message, it means your computer was unable to read the installation archive files. Let’s first look at the method that has helped most users to fix the isdone.dll problem with the Unarc.dll error code when unpacking, and then we’ll look at workarounds for this error.

How to fix ISDone.dll error with code Unarc.dll in Windows 10

First, let's look at a method that helps in most cases - this installing the game in safe mode. Large games have a huge collection of files and they create conflicts with pre-installed drivers and third-party software. Once you enter safe mode, all these apps will not load, so there is free space to play. Therefore, installing the game in safe mode will save you from all unnecessary processes and memory. To do this, let's follow some steps.

Step 1. Press and hold " Shift" on your keyboard. Now restart your computer. To do this, click " Start"on the taskbar, then on the icon" Shutdown" select "". You can read the full manual, .

Step 2. After restarting the computer, install the game in safe mode that displays the error.

Step 3. After installing the game, you need to exit safe mode. To do this, press the button combination Win+R and enter msconfig.

Step 4. in the window that opens " system configuration", go to the "Boot" tab and uncheck "Safe Mode". Click apply and "OK", then restart your computer or laptop and enjoy the game without ISDone.dll and Unarc.dll errors in Windows 10. If this method does not help , then consider below 2 methods related to RAM and DLL.

1. Solutions related to RAM (RAM)

Let's consider the method with RAM, which is the culprit of the ISDone.dll error with the code Unarc.dll in Windows 10.

Increase paging file size

Large games take up GB, so the RAM does not have enough space to fill the required space. Windows uses part of the hard drive as virtual memory and is called . Hence, increase its capacity and make sure that the RAM matches the requirements of the game.

Step 1. Click the buttons Win+R and enter sysdm.cpl to open system properties.

Step 2. In the new window that opens, go to the " tab Additionally" and in the performance section, click " options".

Step 3. Click on the " tab Additionally" and below in the virtual memory section click on " Change".

Step 4. In the Virtual Memory window, uncheck " automatically select the size of the paging file". Next, select the dot " Specify size" and specify in the columns minimum 100 And maximum 3000 size. Please note that you can increase the size if the game requires more. Now click OK and the system will ask you to restart your computer to make the changes effective. After rebooting, run the game installation to check if the isdone.dll error is fixed when unpacking the game and if the Unarc.dll code is returned.

Delete Temp files

Step 1. Press the button combination Win+R and type in the field %TEMP% to reveal the location of hidden temporary files.

Step 2. Select all files that are in the folder temp and delete them.

Run the Windows Memory Diagnostic Tool

After increasing the page file size, a persistent error indicates that there may be something wrong with the RAM. The Windows Memory Diagnostic Tool will clear your doubts, so run it on your computer. We will briefly discuss how to run diagnostics, but you can look in more detail at the link.

Step 1. Click "start", type mdsched.exe and run it.

Step 2. In the Windows Memory Checker dialog box, select " Reboot and check (recommended)". After the restart, a blue screen with a test for RAM will appear. If serious errors occur in the test, you will most likely have to replace the RAM stick. See the link above for more details, it describes how to fix the errors and what they relate to.

Run Disk Cleanup

Windows installation files many times add garbage in addition to system files. The game installation process may be interrupted by a clutter of junk, old files, so running Disk Cleanup would be a good idea. Although a guide already exists, we will look at it briefly here.

Step 1. Click Win+R and dial cleanmgr to launch the Disk Cleanup tool.

Step 2. In a new window, select the system disk to clean it of debris.

Step 3. Check the box next to everything on the list and click below " clean system files". In the next window, also mark the entire list of files to be deleted and click OK to remove junk from the system disk.

2. Solutions related to DLL files

DLL shows dynamic link library which helps to perform multiple tasks in Windows operating system. The System32 folder on the installation disc contains all the DLL files that are assigned to various functions. Usually games contain all the necessary dll files, but when you have a pirated or corrupted game, this causes various errors, usually with missing libraries. If you find ISDone.dll error on Windows 10 PC, then here are some working solutions.

Disable antivirus

Windows Firewall and Windows Defender protect the system from malicious files, but sometimes they prevent the installation of a genuine game due to certain restrictions. After that, disable both security applications to check if the error when installing the game is resolved.

Third-party antivirus also creates conflicts with game installation files, so disable or uninstall it if present.

Step 1. Go to Security Center settings and disable your antivirus. To do this, follow the following path All parameters > Updates and Security > windows defender > Open Windows Defender Security Center. Next, click on the icon " Protection against viruses and threats" and select " Antivirus and other threat protection settings". Drag the sliders to the mode Off. Thus, Windows Defender is disabled, so now focus on disabling the firewall.

Step 2. In the same Security Center window, click on the " house"cabinet and select" firewall and network security".

Step 3. You will see "Public Network", "Private Network" and "Domain Network". Click on each of them and drag the slider to Mode shutdowns. Now make sure that the ISDone.dll error in Windows 10 does not occur during the installation of the game and the Unarc.dll code is not returned.

Run System File Checker

Running the SFC tool to repair damaged system files is also a great way if the above solutions did not help. SFS will scan system files and, if possible, restore damaged ones if it detects them. See the complete guide to .

Step 1. Run Command Prompt as Administrator.

Step 2. At the command line, type sfc /scannow and press Enter. The process may take a long period of time, you can drink a cup of coffee. Restart your PC and make sure that the ISDone.dll error when installing the game disappears and the Unarc.dll code disappears.

Re-register the ISDone.dll file

A damaged ISDone.dll or Unarc.dll file is the root cause of this problem, so you need to re-register it. In the previous process, you have already learned how to run the "command prompt" with administrator rights.

Step 1. Issue the command on the command line regsvr32 Isdone.dll to re-register the ISDone.dll file.

If you find that an error occurred during unpacking: The archive is damaged unarc.dll returned the error code ERROR: archive data corrupted (decompression fails), then also run the following command in CMD regsvr32 unarc.dll .

Download the ISDone.dll and unarc.dll files

This is a proven solution if DLL files are missing or not working properly.

Step 2. Go to the page https://www.dllme.com/dll/files/unarc_dll.html if you receive an error message unarc.dll and download the file.

Step 3. Then, when the downloading of both files is complete, right-click on each of them to extract or unzip.

Step 4. Open the system drive along the path C:/Windows/System32 and copy these files there.

I hope that you have fixed this ISDone.dll error with the code Unarc.dll when installing the game on Windows 10.

3. Solution to launch the game or program installer from the TEMP folder

In the comments, one user under the nickname Pavel Panchenko shared an interesting method. If the above methods did not help you, then we will look at another solution to this problem. The bottom line is that you need to put the game installer itself into a temporary windows folder" TEMP", let's figure out how to do this.

• Press a combination of buttons Win+R and enter %TEMP% or follow the path by enabling C:\Users\username\Appdata\Local\Temp

• Copy the installer ".exe" of the game or program and place it in an open temp folder. Next, simply start installing the game from the temporary folder temp. If it gives errors, try running the installation as an administrator by right-clicking on the installer itself. After successful installation, you can delete the installer itself so that it does not take up precious space on the system disk.

Very often, such a problem appears at the most inopportune moment, so this article will cover problems that relate to typical unpleasant situations and ways to deal with them.

While the long-awaited toy is being installed, you suddenly see a new window with a failure notification. Then we can say that an error occurred when unpacking Unarc dll returned error code 1, 5, 6, 7, 8, 11, 12. But how to fix this problem?

If you look at the translation, you can understand that Unarc.dll returns an error code, and a number is written indicating what kind of problem occurred. As for the reasons for the appearance of such a window on the screen, there are a lot of them, so below we will consider the most common errors, causes and ways to get rid of them.

Corruption of the installed file

The first step is to carefully study the text that is written in the error window, and if there are the words “CRC check” or “problems with file integrity,” this means that the file has been damaged. To make it clear, you should pay attention to the first drawing.

And this happens for several reasons:

In the latter case, you can simply contact the program that installs this file and, perhaps, it will be able to fix the problem. But sometimes it is possible to simply download this file from another source and install it again.

PC problems and their solutions

Having looked at the frame with the error and noticing that it does not say that the file is damaged, we conclude that in this case the problem will be more difficult to solve. Typically, such windows appear with code number 7, and it indicates file decompression. There are a variety of reasons for this problem, which will be discussed below, and as an example, the second figure is shown, where you can see the problem.

No required archiver

You can find out which archiver is needed from the same error. In this case, you just need to download it. If the archiver is not specified in this window, then you need to download the most famous ones, for example, 7-Zip, WinRar or WinZip. The link is given below!

Lack of free space on the hard drive

Usually, none of the inexperienced users even checks the hard drive and the availability of free space. In this case, you need to know that if a game requires 5 GB, then you will actually need that much to install it, but more for the game. This is because once the toy is installed, temporary files will be created as it progresses. Therefore, it is necessary to first clean the hard drive and make room for the game. This situation can be seen in the third figure.

Cyrillic or other characters during installation

Users who are more experienced and have been working with a personal computer for a long time remember how many files did not work correctly with Cyrillic and other characters from our language. Due to the fact that “jambs” appeared when naming a particular folder, Latin letters and designations were used in its name.

As for our time, the situation with the Cyrillic alphabet has improved significantly, and almost all errors have been corrected, but it is recommended to install the problematic game along the path where only Latin letters are located. An example is below.

The correct way to install the game.

Incorrect installation path.

Having problems with RAM

Many people believe that if they don't get errors when working even with the latest version of Windows, then it works well and there are no problems. But we need to dispel this belief and say that this is far from true. After all, if you pay attention to the RAM, then in almost all cases you can identify any problems in it, even if the hardware is working perfectly.

In order to identify something wrong with the PC memory, you need to pay attention to the following phenomena:

• the appearance of a blue screen with a huge number of incomprehensible symbols and letters (also known as the “blue screen of death”).
• very often the computer freezes and does not respond to absolutely all keys;
• sudden reboot of the computer without any action by its owner.

If the above problems are identified when working with a PC, then it is worth optimizing its operation.

Page file is disabled or too small

In order to make any changes to the paging file, you need to open the "Control Panel", which can be launched through the "Start" menu. After this, you should click on the section called “System”, as shown in the figure below.

Having opened the “System”, you need to turn your attention to the left side of the screen, where there is a link called “Advanced system parameters”. You need to click on it. In order to better understand the process, look at the picture.

After these steps, you need to open the "Advanced" tab and the "Performance Options" menu, as this step is shown in the figure below.

In the "Performance Options" section you can change the size of the paging file. Its size remains a topic for individual debate, but based on this article, it is recommended to rely on a size twice the amount of RAM.

Conclusion

We have no doubt that this article was useful for every reader and helped shed light on some of the problems that many face when installing their favorite games and other applications. If the above explanations and steps for solving problems that may accompany the installation of files helped you solve all the nuances that arose during the installation of something on a PC, then share the article with your friends and rate it.
