I’m looking forward to deploying PowerArchiver 2023 to my users. Can you tell us when the MSI will be available for download and distribution?
Thanks.
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

Hi there,
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?
Hi,
From where I get PAVD2023.EXE? PowerArchiver 2023 tries to open it.
But it seems, it tries to download PAVD2021.EXE.
Thanks
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)
PA 21.00.18 running on Windows 7 64 bit.
I made a big .PA file and thought I’d check it was made correctly with Menu / Actions / Test.
Discovered:
a) PA always issues a UAC prompt to do this!
b) PA always says there are many errors in PA files.
Major 7zip update fault
-
Whilest updating two archives with microsoft access files in them one had several word files and two access databases in it and the other, one access database and a hlp file.
to my horror it had a problem upating due to the fact i clicked on one database in side the archive whilst the archive which was the largest one was updating itself. It failed coming up with an error saying could not update itself. So I simply added it again, then I updated the smallest archive. Then I decided to update the largest archive again and to my horror it had been over written by the smallest archive.
I thought I might have done something. To my hoorror the smallest achive whch i had not opened just then was empty.
Luckily I had done backups on usb stick.
Should this happen ever no the two archive with different names but same extension had cross threaded for some reason and changed. the largest archive contense had disapeared and the smallest one was empty.
Seem to be a major fault with 7zip format.
I have re checked and checked again and can not at this time reproduce the events but it is a major worry that this can happen at all. Is there any safe gaurds in 7zip / powerarchiver to stop this happening ever again. Or is it best to avoid 7zip that can upadte itself. should we only use 7zip solid infuture or is ther something wrong with the 7zip updateing of archives.I have windows 2000 with latest updates and latest version of powerarchiver.

I will print this out and read it very carefully :-)
