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.

  6. i m trying to install 'Call of duty black ops 2' i have a free space of 80GB but in the middle of the installation it shows an error 'unarc.dll returned an error code:-7' and the installation get closed. What i do to install that game the same DVD file is copied to another PC and it runs.
    plz help me....

  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.

  10. "an error occurred while unpacking: archive corrupted/unable to read data ! unarc.dll"
    this error occurs when i try to install...does this mean the setup file is corrupted and that it has to be replaced...is there any other way to solve this problem...pllzz reply...thanks in advance.

    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.

    "unarc'dll an error code :-7

    please help me out bro

    ReplyDelete
  17. Error Code 5 stands for "ACCESS_DENIED"

    Error code 6: "INVALID_HANDLE"

    Error code 7 means Storage control blocks were destroyed

    The above error indicates that archive is corrupted (or) the archive contained DVD is corrupted.

    Try to recover DVD contents using some free DVD copier/recovery tools.

    If u feel the above process is time consuming then replacing is the final option.

    ReplyDelete
  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.

    ReplyDelete
  35. I cleared the temporary memory and disabled all the firewall, anti-virus real time shield but the installation alway stop at 83.8 per cent with the following message: An error occured while decompressing: Archive Header is corrupt! Unarc.dll returned an error code:-14

  36. Thanks for the help! I will give it a shot

    ReplyDelete
  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.

  47. 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.

    ReplyDelete
  48. If the Game doesn't install in another PC then the problem is with your Game Setup file.
    Try to download a fresh copy of the game and install it.

  50. Since the header file is corrupted you cannot decompress it. If your setup file comes with many files then install it. Otherwise download a new setup file.
