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.

PA 22.00.06 (PA 2023)
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.
I installed powarc-macos20001.dmg and I am attempting to create a password protected zip file. When I create the zip in the UI it doesn’t write the file to the destination folder. No error message is displayed. The PA app has full folder permission. I’m new to Mac, but have been running PA on Windows for a long time.
Will there be a new version of the Mac version soon?
Hi! I came across an issue when I tried to uninstall PowerArch 2013. I got an error “The specified account already exists” which broke the process. I got the same error when I tried to install the current version, without uninstalling the previous one.
So I can’t uninstall and I can’t install PowerArchiver. Any suggestions? OS Windows 8.1 x64.
This appears to be happening again with the Power Archiver 2022 shell extensions.
When I have Use Explorer Shell Extensions enabled in Power Archiver Configuration and right-click on c:\Users\username\Start Menu, (hidden Junction file), File Explorer crashes.
I have version 21.00.15 (03/2022) 64-bit installed in Windows 10 Version 21H2 (Build 19044.1826).
The online update feature within the program suggests there is a later version than the ‘.17’ available on the web site. But clicking either download or update just reinstalls version .17.
Either there isn’t an update OR
the “download” and 'update" links should be repaired.
When you click on the Buy Now link, you come across four tabs - Home or Work, Enterprise Unlimited, Educational Discount, & Gift Discount.
What is the difference between a licence purchased via Gift Discount and a Home/Work licence?
Also, how can I renew the PowerArchiver Select plan a year after the purchase? Will it remind me automatically?
Self Extracting Encrypted Archive
I was hasty creating a self extracting encrypted archive at one point. I may not be able to get to the original files. The file size is over 4GB and Windows XP indicates that it is not a valid format. Is there a way to manually access this file of course assuming one supplies the correct password?
I did try to rename the extension to .pae but PA gives a message about unknown encryption method.
1st thing you need to do is atempt to fix the file in order for PA to recognise the format/encryption once you have done that then try entering the apparent password.
However, on the chance the algorithm’s have been damaged due to a “hasty” creation or another reason then unfortunatly the bad news is it will be difficult and pritty much impossible to know where to start.
ie… the container code which instructs applications such as pa on how to read the data or the encryption method.
Hope you do find a way and if so let us know.
What do you mean by fix? THe only option i find relating to that is to fix a zip file. This is an encrypted, self extracting executable.
Sometimes you can fix a self extracting file via windows notepad as I have in the past. But most the time if the file is badly currupt then its a no win situation.
Unfortunetely, the fix function in PA wont work on such a file.
we will see - you might be able to strip the .exe header, if that is possible. As you know by now, windows file system limit for executable files is 4GB.
Did you try opening the archive in PowerArchiver?
Tried Hex editing the beginning of the file with some test files but was not successful. These were about 4MB. When I renamed the file from *.exe to *.pae it seems to see the file within PA but gives a message about unknown encryption method. I was going to try adding the name of the encryption method similar to a normal .PAE file.
did you simply try opening .exe file with PA? I am not sure if that was ever added
The way the information is encoded seems different so no go there for now though the SHA-1 hash for the password is the same.
I got it with a smaller test file.
Use the part from a .pae file using the same encryption method and password. The file name matters not. Take the beginning of the .PAE file including the seemingly blank space “0D0A0D0A”. I was leaving this as “00000000” originally. Add the part starting with SHA-1 from the .EXE file and save the combined as a .PAE file and voila. I’ll have to try the larger file later tonight.

Now that will be good Entertainment! :D

Now back to our regular programming:
What one has to do assuming one knows the password:
1. Create a “.PAE” file with the same encryption method. The password HASH from the executable file matters. Even using the same password, the hashes can differ and PA would think it is the wrong password.
2. Take the header of the “.PAE” file ending at the end of "SHA-1 ". The space is “20” in hex. Copy this into the beginning of the executable file.
3. Cut/Delete the portion after the newly pasted "SHA-1 " up until the end of the "SHA-1 " the was originally in the “.EXE” file.
4. Erase all but 4 bytes of emtpy space “00000000” after the hash in the “.EXE” file.
5. Rewrite the remaining 4 bytes of empty space to “0D0A0D0A”. “0D0A” is used as a separator.
6. Save the file as “something.pae”.
The name indicated in the beginning of the file does not matter though it will become the name of the decrypted file.
I used HxD Hex Editor which can handle files larger than 4GB. Not all hex editors can.
good, good… I am glad you figured it out.
Is it possible to have PA warn the user when the file size may go above 4GB for an executable? That way they will be made aware that there may be an issue for them?
