When installing a program (usually a game repack), the user may encounter an error unpacking it and the corresponding message “Unarc.dll returned an error code”, followed by the number of the error itself (most often - 1,6,7,11,12 ). Re-installing the problematic repack also ends in nothing, forcing the user to search the Internet for tools to solve this problem. In this material, I will try to help such users and tell you what to do if Unarc.dll returned error code -1,6,7,11,12 when installing the game, what are the reasons for this dysfunction and what to do in this situation.
ISDone.dll - An error occurred during unpacking
As mentioned above, the Unarc.dll error with codes occurs when installing any game repack on your computer (most often downloaded from torrents and pirate sites). As follows from the text of the error itself, it is associated with the use of the dynamic library Unarc.dll, designed for unpacking various archives.
Accordingly, the already mentioned text “Unarc.dll returned an error code” appears in conditions when it is not possible to correctly unpack these same archives (the archive checksum presented in the CRC parameter does not match the actual one). This is due both to damage to the archive itself and to the use of rather unusual packaging methods using the latest archivers. In this case, regular or outdated archivers cannot cope with unpacking the problematic archive, displaying the error message “Unarc.dll returned error code” -1,6,7,11,12.
The reasons for the error “Unarc.dll returned an error code” may also be the following:
- The installation path for the game on your hard drive uses Cyrillic characters;
- The antivirus blocked the installation of any of the repack components;
- Virus programs are to blame for archive damage;
- Small swap file;
- Problems in the operation of the slats random access memory.
Once we have decided on the reasons for Unarc.dll returning error code, I will list the tools that will help us fix Unarc.dll on our PCs.
How to get rid of Unarc.dll returned error code -1,6,7,11,12 when installing the game
So, if you are faced with the problem Unarc.dll returned an error code, then I recommend doing the following:
- Try disabling your antivirus not only when installing the program itself, but also when downloading it(there is a possibility that your antivirus removes suspicious components of the repack when downloading it “on the fly”). Also disable Windows Defender and SmartScreen (if available);
- Make sure that the game installation path used does not contain Cyrillic characters, if necessary, install the game in another location with the path fully written in Latin. You can also try copying the installer file to a flash drive and installing the game from it (this gave good results);
- Install the latest version WinRAR archiver and WinZip. At the same time, installing the latest version of the 7-Zip archiver turned out to be the most effective in this regard - the latter showed excellent results in correcting the dysfunction “Unarc.dll returned an error code”;
- Increase the page file size. Click the “Start” button, enter sysdm.cpl in the search bar and press enter, in the window that opens, go to the “Advanced” tab, click on the “Options” button. There, again go to the “Advanced” tab and at the bottom, in the paging file parameters, click on the “Change” button. Uncheck the automatic selection of paging file, and specify maximum size the latter (usually it is equal to the amount of RAM);
- Try running the program installer in Win XP compatibility mode(you can also try other OS), for some users this gave the desired result;
- Try searching and downloading another repack of the game you want(diversify your sources, take a closer look at alternative torrent trackers, and so on);
- It’s also worth trying to use the program’s functionality Dll Suite, which finds and fixes errors related to dll libraries;
- You need to check the performance of your RAM sticks. To do this, I recommend using appropriate programs (MemTest level). You can also remove your memory sticks from the computer, and by turning them on one at a time (and changing) you can figure out which of them is unstable (or not functional at all).
Conclusion
If a problem occurs, Unarc.dll returned error code -1,6,7,11,12 when installing the game, you should first of all update your archiver by installing the latest version (I would recommend taking a closer look at the 7-ZIP mentioned above). The most effective solution in such situations is to use an alternative repack from another author - often the problem with the Unarc.dll error was fixed only in one specific repack of a given game.
In contact with
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 maybe she can 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 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 HDD and availability 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 the personal computer, remember how a huge number of 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 do not have errors when working even with the latest Windows version 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 " 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 pay attention to left side screen where the link with the name "" is located Extra options system". You need to click on it. In order to better understand the course of action, 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.

When unpacking any archive (repack), the user may encounter an unpacking error and the corresponding message “ERROR: archive data corrupted (decompression fails). This problem can be caused by many reasons, from structural damage to the archive itself to hardware problems in the computer’s memory. In this article, I will tell you what the essence of this error is, introduce the reader to its causes, and also explain how to fix ERROR: archive data corrupted (decompression fails) on your PC.
Screenshot ERROR: archive data corrupted (decompression fails)The essence and causes of the error ERROR: archive data corrupted (decompression fails)
As follows from the error text, which in translation sounds like "archived data is corrupted, decompression failed", the occurrence of this error is associated with failure to decompress (unpack) any archive. This is usually due to the following number of reasons:
How to fix ERROR: archive data corrupted (decompression fails)
To solve the archive data corrupted (decompression fails) problem, I recommend doing the following:
- Check if there is enough free space on your hard drive, if necessary, free up space by deleting a number of unnecessary files;
- Temporarily disable your antivirus and firewall, and then try to unpack the desired archive;
- Disable the Smart Screen system filter on Windows 8 and 10, as well as Windows Defender;
- If the path to the archive has Cyrillic characters, move this archive to a folder whose path has only Latin characters, and try to unpack this archive from there;
- Run the repack as an administrator (hover the cursor over the executable repack file, right-click, select “run as administrator”;
- Try using another archiver to unpack the archive (if possible), or reinstall your archiver using the latest version;
- Try moving the problematic archive to another PC and unpacking it there. If everything goes without problems, then the problem is in your PC, but if problems arise there too, then the archive itself is damaged;
- Try downloading this archive from another source (or from another repack author). Quite often, when unpacking a certain archive from a specific author, the problem archive data corrupted (decompression fails) appears, while a repack from another author can be installed without any problems;
- Check your system for viruses. Tools such as Dr.Web CureIt!, Trojan Remover, Malwarebytes Anti-Malware and a number of other analogues;
- In some cases, archive problems are observed due to the media (for example, a flash drive) on which the archive is transferred. Try using an alternative medium;
- Check your computer's memory with special tests (Memtest level). You can also try removing memory sticks one by one and starting the decompression process, which will allow you to identify an unstable memory stick.
Conclusion
Reason ERROR errors: archive data corrupted (decompression fails) usually means damage to the archive file itself. To solve this problem, I recommend using the tips I listed, this will help get rid of the archive data corrupted (decompression fails) error on your PC.
Many fans of computer games often have a problem when, when trying to launch an application, an error appears with the inscription “Unarc.dll returned error code 6.” Not everyone knows what to do in this situation, since basically it is relevant only for those users who download repacks or install games from disks purchased at a reasonable price.
Moreover, if Unarc.dll returned error code 11, 12, 6 or some other number, many believe that this library is damaged and you just need to download it from the network, and then move it to the desired folder, which never really helps in a situation like this.
Under no circumstances download libraries separately from third-party resources.
How to identify the problem?
In this case, you need to study the error that is given to you in more detail. It is worth noting that you should not look at whether Unarc.dll returned error code 12, 6, 10 or some other, but at what is written next. For example, in some situations, “failed CRC Check” is written, which indicates direct damage to the desired archive and, accordingly, incorrect downloading (or distribution) of the repack.
- 7-Zip;
- FreeArc;
- NanoZIP.
In principle, the above options can eliminate almost any problem with Unarc.dll returning error code 14 or another number, but there are other problems.
What else could happen?
It is worth listing a small list of popular problems:
- Cyrillic characters in the path to the game folder.
- A small swap file.
- Damage to the RAM board.
All these problems can be eliminated quite simply, and at the same time they are rarely the real causes of this error, so you should pay attention to them only as a last resort.
When extracting from the archive and installing repacks pirated versions video games and computer programs users encounter unarc.dll library errors. This problem is common among gamers and appears on computers with Windows 7 and 8. The error code may be different, the main thing you should pay attention to is the notification text in the sign. If you see such an error, do not rush to download RePack games again or from another source, even if you see a message that the archive cannot be unpacked because it is damaged. In fact, there is a 99% chance that everything is fine with the game or program files. Here the matter is different. And to figure it out, you need to pay attention not to the error code, but to the message after ERROR.
This is how the error is described in this screenshot:
If the description contains the words “failed CRC Check”, it means that the downloaded archive actually has errors (it is damaged and cannot be unpacked). What to do in such a situation is clear: download the assembly from another site and unpack it. And if the error description contains the words “decompression failed” (see screenshot below the text), everything is fine with the archive and we look for the problem on the computer.
If you see in the notification sign that “unarc dll returns error code 7,” it means that your computer does not have the archiver program necessary to unpack the game files. Often such errors occur when installing pirated versions of programs and computer games. Licensed assemblies contain all the necessary libraries, since the developers do not set themselves the goal of reducing the size of the archive with files. Also, during assembly, official games and programs are archived using proven “packers and unpackers” of files. But when creating repacks, “pirates” often archive large volumes of games using non-standard archivers that have a high compression ratio. Most often used:
Downloading a universal archiving program or a new game build solves the library problem unarc.dll in 92% of cases. And the remaining 8% are individual problems. If the methods we suggested did not help you, look for a specific reason. Let's look at them in more detail.
Cyrillic in the folder name
This is one of the most common installation problems, by the way. computer game. If the folder where you install a game or program contains Russian letters, errors may occur during installation or startup.
The solution in this situation is simple - write the English name of the game and reinstall it. Perhaps this will solve the problem with installation or startup.
Incorrectly configured pagefile.sys (Windows swap file)
You should look for the cause of the error in the OS swap file. This system file may be incorrectly configured (insufficient in size) or missing from the system altogether (you deleted it for some reason). When you unpack a game that is too large, the system uses RAM and page file resources. If the volume is too small, you will see a “decompression failed” error message. There is only one way out - configure pagefile.sys.To do this, click on Win+R and enter the following command in the window: sysdm.cpl
On the "Advanced" tab, go to "Options":
From there, go to the “Advanced” tab, where you need to select the “Virtual Memory” section. To change its parameters, click on the corresponding button. You will see a window:
The volume for the paging file is selected in automatic mode, as evidenced by the checkbox next to the corresponding item. Uncheck this box and select a disk location for the paging file. It is advisable not to post it on system disk. It will be optimal if the paging file is placed where there is the most free space. Now we need to specify its size. It should be equal to the amount of RAM. Once you have decided on the size, click on the appropriate button to change its parameters. Save your settings.
RAM (random access memory)
This reason is rare. Possibly due to a library error unarc.dll caused by a malfunction of one of the RAM sticks. To check this version, use two options. The first one is not fast, inconvenient and not suitable for untrained users. First, remove all RAM modules, and then turn on one at a time and check whether the archive with the game or program is unpacked.
The second option is faster and more reliable. You can use special utilities to check RAM modules. We recommend for advanced users. Beginners can test RAM like this:
Click Start and write “Diagnose computer memory problems.” Clicking on the icon will open a window:
Conclusion:
Library downloaded to PC unarc.dll will not solve the problem, perhaps it will only change the error code number. If the methods we have discussed do not work, there is only one way out - to reinstall the system.
