Win 11 64 bit
I have some archives which have been encrypted, using the encrypt option either in pbs or when interactively creating a zip. When I open these, and look at files, I am asked for passwords, which I know, and then can view items or decrypt the files in the archive (tools>decrypt files).
However, when I use the Actions>Remove Archive Encryption (whether using the same zip or asking to write another), the routine shows progress bar to the end, but then just hangs i.e. “OK” never activates. All process information shows this stalled/hanging.
What can I do to sort this out?
Download this ZIP file: http://dslstats.me.uk/files/dslstats32W-6.5.zip
Everything in the ZIP file is in a directory “dslstats32W-6.5”.
However when I extract using right click “Extract Here” the name of the directory created is “2W-6.5” !
I am running PA 22.00.09 on Windows 11. I have seen the same happen with some other kinds of archive too.
If I compress a folder to a .pa using right click, Compress to folder.pa and use the new Windows 11 menu then the Options, Configuration, Miscellaneous, Use normal relative path setting is always enabled.
But I like this option disabled so I have to use the old style menu in order to get PA to compress a folder in the way I wish.
Just tried using the Modern (Windows 10) Icon set and seeing a few missing icons in both PowerArchiver Burner and PowerArchiver Encryption screens . They are all there in the Minimalistik icon set and the only difference I can see is the former is blue and the latter grey. In version 22.00.9
there were some security issues fixed in 7zip:
As it seems, that PowerArchiver and PACL use the 7zip libraries, could you please update them to the latest version?
I noticed that the version of ZPAQ used is older than the latest released 7.15 https://mattmahoney.net/dc/zpaq.html also there seems to be a newer fork that adds several features https://github.com/fcorbelli/zpaqfranz
It would be useful to implement this latest version (it also maintains the same syntax and behavior as the latest official release if used the -715 flag) and add when opening a zpaq file a choice of the version of the files to show (e.g. as dummy folders represented the various versions present). Since any previous changes are stored with this format, it is possible to extract a snapshot of a certain date/version.
If I open a password-protected zipper file (created with WinRAR but I think that’s irrelevant), open it with PowerArchiver and run “Remove Encryption” on the same file, then reopen it and add a password with “Encrypt Archive,” the resulting archive will be protected with the old ZipCrypto algorithm and not AES as indicated.
(this can be verified, for example, by trying to open the archive files with Windows Explorer, which does not support the AES algorithm)
When I uncheck the option to associate PA with archives, it still tries to do so!
How do I know this? Well, I installed PA on my university PCs. Every student who logs in has most priviledges stripped. One of them is writing to the registry.
The installer gave errors, most of which had to do with HKEY_CLASSES_ROOT.
Now, HKEY_CLASSES_ROOT deals with file types and associations, right?
So then this is an installer bug! I even unchecked all 3 boxes, but it yielded the same result! Please fix this!
No, thats not actually it I dont believe :-). It is PA hiding one of the options (lets not mention which one). There is no way to install PA properly without writing to the registry in any case (among other things, you would not be able to install shell extensions properly).
I do suggest that you check if any association has been changed, before writing an post about it :-).
Even when you disable option to associate PA with archives, installation tries to write to HKEY_CLASSES_ROOT some other things - information about shell extensions.
So, don’t worry - file associations are not rewrited. And if user (in you case students) are not able to write anything to HKCR then he just won’t be able to use shell extensions. All other things will work fine.
PA supports many hidden options for installation on networks and multi-user environment. Contact us via mail more for information about configuring PA in multi-user environment.
