unarc.dll error while installing large application file

[last Updated on 26th June, 2013]

Error 1:
"unarc.dll error" appears while installing/extracting large or highly compressed file especially for Game.

This error appears because you have only limited free space for installation/extraction even-though the installing application shows enough free space.

To avoid this error, you must have at least free space of 17.5GB in your drive where you want to install and run.

Info:
unarc.dll is used for decompression of files like installers, installer scripts, archives etc. This dynamic link library file is created along with the software/game application in order to decompress the software/game during installation in Windows based PC.

This procedure is similar to decompression of .rar files using winrar but quiet different.

For example: if you try to extract a .rar file of 2GB but the actual size is 4GB and you have only 3GB of space in your drive, then winrar displays a error message stating that "there is no space in drive" (or) Windows will displays a error message stating that "winrar encountered a problem/winrar.exe error".

The above example is very similar to unarc.dll error.

So [winrar.exe for eg] unarc.dll error will not appear if you have enough free space for installation/extraction and if still appears then you have to increase your free space.

Error 2:
Unarc.dll also reflected as "an error occurred while unpacking: archive corrupted/unable to read data (decompression fails)! unarc.dll". Which is quite different from the above error.
 
This error occurs due to that the software/game setup has some corrupted installers, archives etc so that it cannot be extracted by unarc.dll. 

The following codes indicate different issues based on your specs, OS type or even the setup file itself.
Code 1: "INVALID_FUNCTION" and your archive is corrupted
Code 2: "FILE_NOT_FOUND" (i.e) unarc cannot find the file specified
Code 3: "PATH_NOT_FOUND"
Code 5: "ACCESS_DENIED"  
Code 6: "INVALID_HANDLE"
Code 7: "STORAGE_BLOCKS_WERE_DESTROYED"
Code 11: "BAD_FORMAT"
Code 12: "INVALID_ACCESS"
Code 14: "OUT_OF_MEMORY"

To avoid this error, try to install the software/game with a new complete setup file which is genuine.

Note1: Don't install any ultra high compressed game.
Note2: Don't install any pirated game.
Note3: The downloaded iso image files of game from any torrent site may work 100% but not for all types of OS with different versions.

    1. How to fix error that say "checksum of decompress file is not same like checksum original data"? I have enough space.i got this error when i trying to install crysis 3

      Delete
    2. I think sometimes it happens because of computer user names that contain non english characters.I had same unarc.dll problem and carried far cry 4 folder to C:\ and it worked.It worth trying at least you won't lose more than 2 secs.

      Delete
    3. when you said "you must have at least free space of 17.5GB" are you counting the installed game 's size or do you mean Setup +after install game size+17.5 GB EXTRA????

      Delete
    4. i put the game of which is being set up at a different location
      i think it should work

    1. It means certain sectors in your harddrive is dead. I'd recommend just running a defrag and hoping for the best, or if you've got more skills, launch ViVard off of HiRens and let it clean up your sectors.

  7. @ Neo Anderson:
    if you receive error message like "archive Data Corrupted(decompression fails)" along with the error code 7, then the files in the DVD might be corrupted. Try to copy those files from DVD to hard disk and then install your game from Hard Disk instead of running from DVD drive. This might help to fix your issue.

  11. @Festim
    Error code 1 stands for "INVALID_FUNCTION" and your archive is corrupted. Try to install the same game in another PC, if it works fine then the issue is with your PC else download a fresh copy of it.

    @anonymous
    The only way to fix is by replacing a new setup file. The other method is too complex which may help but i'm not sure that it works 100%.

    ReplyDelete
  12. Error code 3 stands for "FILE_NOT_FOUND" (i.e) unarc cannot find the file specified.

    Replacing a new archive/setup file might fix this issue.

  29. This error states that the unarc decompression method is not compatible with the versions of Windows. Try running the setup in another PC of different version of 32-bit Windows. If that doesn't helps you then the files inside the archive (i.e) setup is corrupted.

    ReplyDelete
  30. I assure that this checksum error clearly indicates that the setup file is badly compressed (i.e) corrupted. The corrupt file is GLOBALEFFECTS.bndl. Try to download a fresh copy of this game since we cannot skip this file alone during decompression or installation of the game.

  34. Just clear your temporary memory. Disable any firewall, anti-virus real time shield. Make sure you are installing NFS from hard disk, sometimes installing from dvd or mounting image using DT have some issue. Try to have more storage space since error code 14 is more related to storage issue.

  37. The following were the causes:
    1. You haven't completely downloaded the game (or)
    2. The download may stuck @ some % and afterwards you may resume it (or)
    3. The contents inside the game dvd are not fully written (or)
    4. Downloaded game size is lesser than the source file size.

  46. Try to install the game in another PC. This error indicates "Invalid status" which means there might be a problem in your hard disk.
    1) Open Command prompt > type CHKDSK /R and hit Enter.
    2) When the check disk command finish checking your hard disk.
    3) Find any bad sector files when it reports.
    4) If the bad sector files are fixed, then reinstall your game.

  47. If the Game doesn't install in another PC then the problem is with your Game Setup file.

  104. For error code: -14. Is an antivirus problem. Make sure you have disabled your antivirus and Windows Defender. For Windows defender go to Control panel--> Windows Defender--> Tools-->Options and uncheck "Use this program" in the las tab.

  109. I know this is old but it helped me, I recently bumped my Overclock from 4.2 to 4.5ghz and all found it to be "stable" but kept running into error 7 if i didn't clear my temp files and 12 if i did clear my temp files. So I went back to my original OC at 4.2 and it worked, so after to confirm this I uninstalled and bumped my clock back to 4.5 and clearing my temp files I got error 12 again. Thanks Banana !!

  110. If you are getting error 7 clear your temp files (Win-Key +R and type %TEMP%) delete them all some wont delete just hit skip it's fine. Then try reinstalling if you run into error 12 after doing this then it's because of your Overclock being unstable. So reboot into your BIOS and set it to default, reboot, clear temp files and it should install no problem. then you can overclock again.

  115. Guys, maybe, just MAYBE there is a problem with unarc.dll. try getting dl files fixer, and downloading unarc.dll and isdone.dll. (also, if you manage to get your hands on the full version, check your registry). Once i did this, around 40% of my games started installing fine. The rest, i suppose, are corrupted

  116. Far Cry 4 - got an error -7 - tried several times - always give me this error in after few minutes.

  117. Hi everyone. Solution: I have tried many times with errors, but finally got it. The thing to do is stay connected to the internet, turn off all antivirus, defender, firewall and rename your Hosts file (don't forget to rename it back afterwards). I suggest doing this, rebooting your computer then shutting down all other programs. During the installation there will be incoming and outgoing connections, but if even one of these is blocked it won't work. I suggest installing all of your games at the same time and then turning on all antivirus, renaming your hosts file back to hosts and activating firewall etc. Block everything in the folder through firewall after you have checked that everything works. Hope this is clear, as we say here in South Africa, keep trying!
