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:
https://www.zerodayinitiative.com/advisories/ZDI-23-1165/
https://www.zerodayinitiative.com/advisories/ZDI-23-1164/
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.
7z shell extensions
-
if i slect a filke say 8 mb tand click on 7z name7z for example it starts to work then slows right down after about 58 %
however if i select 7z + options and then click on the 7zi file is created ok no problems
the file i’m archiving is a setup.eng (avast antivirus setup file)
I’m using windows 98 se
-
does it just slow down and completes or does it hang there? If it completes, is it the same size as in + options or? It is possible that using it directly activates the ultra option which is slower, while + option uses something else?
thanks,
-
it slows down and hangs i nbever got further than 58%
the + option uses normal compression and works fine
-
Have you tried compressing it with the + option and then using all the avaliable compression levels ?
-
it slows down and hangs i nbever got further than 58%
the + option uses normal compression and works fine
Try using + Option and Ultra compression - what happens then?
thanks,
-
p.s. I could not reproduce this with my copy of Avast setup
-
does pa use ultra for its shell extensions as normal work fine from the _option
-
When checking Options / Configuration / compression profiles / create new
the “profile1” for 7z is set to Ultra so this may be the default which is used in shell context menu.The help file says
When you first install PowerArchiver, it will create a default compression profile for each format. These profiles can not be deleted and are always saved in PowerArchiver.
What are the settings for these default profiles that PA creates?
-
Default seetings are maximum always (Ultra in this case), but David should check first if Ultra works from + Options, before any conclusions are made.
For me, Avast setup in question works fine at all 7zip settings…
thanks,

Because PA uses the 7zip DLL (ie. 7z.dll) for compression/decompression of 7-zip archives, another thing to try would be to see if the 7-zip archiver itself has any problems compressing Avast.
If it does then it is most likely a problem with the 7zip DLL, otherwise it is likely to be a problem with the way PA integrates with 7z.dll.
-
ultra is the problem would it not be best to have normal used instaed of ultra if the user wants ultra to add it themselves.
