PA 19.00.51 / Access Violation



  • Hi,

    I’m testing the new version.
    My test system is a VM with Windows 10 1903 x86.
    I’m trying to create an archive via context menu. ZIP is working fine, but with 7z and PA format, I get an access violation:

    The archives seem to be created fine.

    Hey @BigMike

    How exactly are you attempting to create the 7z and PA archives when the error occurs?
    We’ll attempt to reproduce using the same steps



  • Hi,

    it happens with any file on the desktop. I’m simply right clicking and then “Compress To 7z” or “Compress To pa”.
    I noticed, that this won’t happen if the file is located in other folders (I tried a network share). I’m using German localization.

    did you have the same issue with .50 or is it something new? Thank you!



  • Actually, I don’t think, I*ve tried this with version .50, so I can’t tell if it’s new or not.

    @BigMike check with .57, not sure if anything changed but there were plenty of changes:

  • Still crashing here in my test VM, but if you can’t reproduce it and no other people report similar problems, maybe something is wrong with my VM!?



  • Hi BigMike,

    If you can enable debug logging for your VM and provide the logs of the crash this would be useful.

    However, these two Module error handlers refer towards .7z and .pa modules, and the fact that you are able to use the application to Zip without error points towards a conflict in the registry where the DLL’s are concerned.

    As such, you are going to want to identify in the logs the DLL’s By name and location that are causing this 1st, and the logging will help with that.

    But my feeling would be you try to de-register the following DLL’s , then reboot your VM and try. (The best way is to check the logs, find the actual dlls and de-register them) But we can try the good old fashioned “go by experience and hope for the best” way too 🙂

    C:\Program Files\PowerArchiver
    7z.dll
    7z64.dll
    pa.dll
    pa64.dll

  • Hi RJWaring,

    regsrv32.exe /u 7z.dll raises an error, that the file couldn’t be unregistered.
    Removing and reinstalling PowerArchiver (I guess, this would de-register them) doesn’t fix the problem.



  • “regsrv32.exe /u 7z.dll raises an error, that the file couldn’t be unregistered.”

    That might be your problem, what VM Application do you use? Do you have system admin rights?

    I can do a bit more digging for you, but in experience 90% its the VM config causing you the problem.

  • Hi, I’m using Oracle VirtualBox 6.0.12 for virtualization.
    My account is an administrator with UAC protection, I ran the command from an elevated command prompt.

    I’m unsure, where to find the problem. The shell extension works perfectly fine in other folders. As I wrote above, the crash happens while compressing files on the desktop.

    As I’m using the VM to test new software, the config might be broken and time to set up a new one.
    I don’t know, if it’s worth to invest more time on the problem, as no one else seems to have the problem.



  • Thanks BigMike,

    I hate to say it , VM has a wide range of documentated cases like these the one’s i know of doing what i suggested helps, but not in all cases.

    Then your talking more time to investigate, which is when the question is raised why not do a rebuild seeing that this isnt an issue being replicated on other VM’s.

    But, it’s not a PowerArchiver problem as i’ve seen this across many other platforms and dll’s.

    Sorry i couldnt help further buddy, if you do manage to figuire it out please share we would love to hear from you again.

    Kind Regards,
    RJWaring
