Remedy No. 2: installing archivers

It was already said above that the more common cause of the error is the lack of the necessary archiver that would be able to work with the format contained in RePack itself. The fact is that many authors who make these archives use “exotic” archiving methods to reduce their weight as much as possible.

The problem occurs due to the presence of a defender on the PC, which blocks the unpacking of the archive and the launch of the game/program. Therefore, you just need to disable the defender. Done this way:

In Control Panel, search for Windows Defender.
After launching the defender, go to the “Options” button.
Disable the defender in the "Real-time protection" section.

Another antivirus may also block the program. Disable your antivirus temporarily, but remember that you will be putting your PC at risk.

The archive was damaged during download.

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 file packers and unpackers. But when creating repacks, “pirates” often archive games with large volumes non-standard archivers, characterized by a high degree of compression. Most often used:

Loading universal program archiving or new build games solves the library problem unarc.dll in 92% of cases. And the remaining 8% is 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 in the window next command: sysdm.cpl

On the "Advanced" tab, go to "Options":

From there, go to the “Advanced” tab, where you need to select the “ Virtual memory" 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. To check RAM modules you can use special utilities. We recommend for experienced 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.

Gamers often encounter the message “An error occurred while unpacking unarc.dll.” It occurs in various operating rooms. Windows systems and says that it is not possible to open the archive with the game or other applications. Often the error is accompanied additional information. Let's look at the main cases, causes of the error, and also determine how to fix it later in this article.

If the error states the reason “failed CRC Check”, this means that the archive file is damaged. In this case, all that remains is to look for the working file. The addition to the error “decompression failed” indicates reasons related to the user’s computer. It is possible that your computer does not have an archiver that works with this format. Moreover, the creators of “repacks” of games and programs often use special formats and programs for the archive. Most often this is RAR, with the ability to unpack using SFX, 7-ZIP with special algorithms archiving ppmd, dcj2, delta, lzma2, FreeArc with unpacking via SFX and others.

Troubleshooting unarc.dll error

First of all, the user needs to download and install a universal archiver on his computer - 7-ZIP. This can be done on the official website of the program https://www.7-zip.org/download.html. Here you will need to select your operating system and its architecture. It works with almost all types of archives.

When installing a problematic game or application, you must carefully select the installation path. It should not contain Cyrillic, that is, Russian letters. The entire path must consist only of Latin characters or numbers. For example, when installing DotA2 in the Games folder, an error will occur. Try canceling the installation, rename the folder to "Game" or something similar to English language and run the installation again.

Replacing the unarc.dll file

If an error occurs during unpacking the archive, unarc.dll returned error code 11 (1, 7, 12, 6, 14, 8),” you must try to replace the file dynamic library and register it in system registry. To do this, you need to download another unarc.dll file from the link https://www.dll.ru/files/search/unarc.dll.

After downloading the file we need, open the folder where it is located and copy it.
Open system Windows folder, then find 2 folders: System32 and SysWOW The file must be inserted into both of these folders.
Launch Command Prompt by pressing WIN+R. In it, enter the following characters “regsvr32 unarc.dll” and press enter.
Restart your computer.

Try running the application with which you were experiencing the error again.

The cause of the error is RAM

Errors during installation and in other cases occur not only due to software reasons. If one of the RAM modules (or the only one) fails, then you will observe various errors when starting or installing programs. Therefore it needs to be checked. This can be done manually.

Open the inspection cover system unit computer.
Find perpendicular installed boards random access memory. Most often they are located near the main processor cooler.
If there are 2 or more strips, you need to remove them all, then insert them into the socket one by one and check for errors. In this case, it is necessary to interact with computer parts with your hands when the power supply is turned off.

If all the strips turned out to be working, let's move on to another method. It consists of checking the availability of computer device drivers. To do this we need to launch Device Manager. You can enter a query in the search bar by clicking the Start button. Open the list of devices and view all items. If there are any problems with the device driver or the driver needs updating, you can see next to it Exclamation point in a yellow frame. If you find such an icon, right-click on it and select the “Update drivers” context menu item.

Other methods to resolve unarc.dll errors

The installation process may be interfered with by Windows Defender and Firewall. Therefore, they need to be disabled, perhaps temporarily.

Open Settings (Windows1, 10). You can find the item by clicking the “Start” button and selecting the gear icon.
Find "Security" (System and Security) here.
Select Windows Firewall and deactivate it.
Next you need to find the “Updates and Security” item. Here, open Windows Defender and select Security Center again.
On the left side of the panel (Windows 10), select the shield icon.
Find real-time protection and disable it.

If additional antivirus software is installed software, then it must also be disabled. Almost all programs have special functions turning off real-time screens for a while. They can be found through the panel quick access(near the volume control and clock). Disable all security on your computer for a while and try installing the application again. The error when unzipping the unarc.dll file should disappear.
