When the function for testing archives is invoked via the shell context menu (PowerArchiver > Test) then all the files in the archive get extracted to the current folder.
The test dialog reports as many errors as there are files in the archive but it fails to give any hint as to which files are supposed to be erroneous or what the nature of the problem might be. Comparing the extracted files to the originals shows no differences at all.
The .7z in question was produced with maximised compression settings in 7zip (taking forever but resulting in smaller archives than .7z produced by PowerArchiver with maximised settings). Therefore I wanted to see whether PowerArchiver can at least test .7z that it produced itself. Hence I had PowerArchiver convert a .pa with the same contents to .7z. There weren’t any errors reported but the resulting .7z contained fewer than half of the files contained in the .pa (137 of 366), so I scratched that test.
Performance is abysmal when testing via the context menu (e.g. almost 2 minutes for testing a .7z that 7zip tests in 4 seconds), but that is most likely due to the fact that the extracted files are written to disk. Testing the same .7z in the PowerArchiver GUI takes only 8 seconds but causes the mysterious appearance of a UAC dialog, as reported elsewhere.
The testing function is vital because PowerArchiver has a history of producing archives that it cannot unpack without errors or that do not conform to the respective file format standards (e.g. ZIP) so that other programs report them as erroneous.
The point of creating archives is that the files in them will most likely have to be extracted at some point. If the extraction cannot be guaranteed to produce correct results then the whole program is absolutely pointless. Actually, worse than pointless - it causes data loss and hence damage.
In PowerArchiver 2023 22.00.06 configuration, the option labelled “Start PowerArchiver 2023 Starter when my computer starts” seems to be redundant.
I am only allowed to change this option when PA Starter is disabled, and then it seems to be ignored.
When I enable PA Starter this option is forced to the enabled state.
I think it’d be good to remove “Start PowerArchiver 2023 Starter when my computer starts” completely. I’ve always found it confusing having both options.
Added later: However i don’t particularly want to use queue but I do like having the PAStarter icon in my tray area.

It has been the case with previous versions of PowerArchiver, but I had hoped that the latest might behave differently. Not so, I’m afraid.
I have, for various obscure reasons, created a few .pa archives, mainly in the hope that they will save me some more space. From time to time, I use the “Test” option to check that important archives are OK and uncorrupted.
With every .pa archive I’ve tested, the process runs through OK but then reports that there are errors. This is always the number of files in the archive e.g. if 11 files, then 11 errors reported.
In the .pa, I can:-preview the files (usually PDF) extract some or all files and look at or use them convert the .pa to a .zip or .zipx archive, which then works fine and tests without errors
Is it the case that the Test routine isn’t designed for .pa archives, or is there another reason? Although the .pa seems to function properly, despite the test reporting errors, I would like to be sure that every .pa is OK and not “broken”.
Some of the .pas are quite old and produced with earlier PA versions (they are truly “archives”). If I extract all the files in the old .pa, create a new, fresh .pa and add back the files to that, then test the new, no errors (at least in the .pa I’ve tried this on) are reported. This would suggest a mismatch between old .pas and newer versions of PA itself.

For some reason, the PowerArchiver functions in the Windows 11 context menu no longer work after the last Windows Update. Only the functions in the classic context menu function as they should.
I’ve tried uninstalling PowerArchiver and using RevoUninstaller to remove all bits and pieces that were left behind and did a clean install of PowerArchiver, it didn’t fix the issue. Other items in the Windows 11 context menu work.
BUG: When using Up/Down cursor keys navigate XPSP2 network install SFX
An error message is displayed saying that “PowerArchiver cannot open this filoe. It does not appear to be a valid archive.”, which is odd because the archive is alreaady open.
This problem occurs with the XP SP2 network install SFX file (WindowsXP-KB835935-SP2-ENU.exe) when using the up/down cursor keys to move up/down the folder tree.
- Open WindowsXP-KB835935-SP2-ENU.exe in PA 9.01 (This can take a while)
- Expand the i386 folder in the folder tree
- Highlight the drw folder in the folder tree
- Use the cursor keys to move down to the images folder, then up very quickly (ie. before the contents of images is read)
** The error message is displayed
This repeatable and happens every time.
I loaded the XP SP2 network install file into PowerArchiver 9.01 and extracted all the files. There were a couple of problems:
The progress window was displayed, but no progress was actually shown even though the files were extracted OK.
After all the files had extracted the progress window was not closed and remained open. The “Minimize” and “Tray” buttons worked (although the PA tray icon was completely white instead of the normal PA icon colours) but the “Cancel” button did nothing. I could also use the main PA window (ie. the progress window had given the focus back to the main PA window)
I will look into XP SP2 problems…
I found some errors in our new CAB SFX support engine so I returned old (from 9.00.xx) CAB SFX engine which should work fine with XP SP2. It is little bit slower because it makes CAB archive in $TEMP folder of original CAB SFX file, but seems to work OK with XP SP2.
I also found that strange behaviour of our new CAB SFX engine depends on installed CABINET.DLL in your system, so deipotent can you please send me CABINET.DLL found in your c:\Windows\System32 folder.
It seems that XP SP2 can be extracted (even progress bar is not shown) with some CABINET.DLL and with some now.
