    Thanks.

    Missing Icons
    LuxorL

    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

    Security vulnerabilities in 7zip / Update for PowerArchiver and PACL libraries?
    BigMikeB

    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

    Better ZPAQ support
    W

    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.

    Bug with "Encrypt Archive" action
    W

    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 Action / Test behaves oddly for me on .PA files
    Brian GregoryB

    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.

      I am running PA 16.00.56 (01/2016).

      I have not had much need to restore from backups, but recently I did, I needed to restore a VM. Part way through, I got a message about a CRC error on a file., and if I continue the VM will not load. The original VM loads ok. Today, I made sure the VM was closed in case that caused a problem, ran the backups, and tried to restore, again got a CRC error, and attempts load generate a dictionary problem.

      I have gone back and repeated this on 3 or 4 previous backups with the same result.

      I checked the logs from today’s backup, could not see any errors.

      So I have no backups???

      Any ideas???

          I can copy the VM to another directory and it loads ok.

          None of my VMs with Win 10 as the guest will reload from backup. Win 7 VMs work ok.

            what VM software? I know vmware asks when open up vm from backup if you moved it (from other computer) or copied it (from same computer).

              VMWare Workstation 12 Player … but it is not getting to there, each time I use PA to backup a VM that is working, then try to restore it I get CRC errors.

                its running during backup? You should try forcing VSS for those files. I am not sure what kind of exclusive access mode is VMP using when running, but it might doing some tricky stuff thats preventing proper access (however it should work with VSS option).

                    i saw both posts, so what does “that is running” refers to? I will have to test it on our lab computer, I dont have Win10 right now only older OSs like Win7, Xp… even 98SE (in VMware)

                        sorry, it says “that is working” not running, I figured out thats what you meant… did you mean simply a VM that works properly when run?

                          Yep, I can load from the original and it “works”.

                          I have taken the external drive out of it, I used PA to back up a Win 10 VM guest (VM not running) to my HDD, then restored to another directory, CRC error.

                          The file that gives the error varies from restore to restore.

                              but win7 VM works fine? What is the size of those? Also, what format did you use in backup?

                                Ok, a bit of progress. This time, to restore, I used File Explorer, ie Windows, rather tha PA … and it worked !!! I feel a bit happier, I have backups again!!!

                                Yep, restoring of Win 7 guest VMs work, I have restored them before, this was the first Win 10 - only been using Win VMs for a few months.

                                Win 10 VM (size on host) is 53.6G, Win 7 is 86.2G

                                Format? All defaults I think, it says Format ZIP (recommended) Backup Type Normal, Method Deflate, Compression Fast, Use current folder as temp is selected, Spanning No

                                    From memory, the dialog said backup completed ok, I looked through the logs, couldn’t see anything, searched for “error”, nothing.

                                    If I can restore with Explorer, doesn’t that mean the backup is ok?

                                    And the one that started it all, normal weekly backup to an external hard drive, that kept coming up with crc errors … just restored it ok with explorer, VM loads it ok.

                                        There is a file Development.vmsd (Development is the name of the VM). Using Explorer it shows in the zip as 0 bytes. It restores ok as zero bytes. Using PA, it shows zero in the ZIP. Attempting to restore generates a crc and a file with 467KB. If an attempt is made to restore that file and it already exists, the warning says it is 4,294,967,295 bytes … hhmmm where do I know that number from? :)

                                          Win 7 VMs do not seem to have zero length files, at least none of mine seem to, but Win 10 VMs do … and that seems to be the problem in PA.

                                          Also, try opening up a zip file in PA, drill down a few directories, then keep clicking the up arrow to go to the parent directory … one too many and PA hangs.

                                              The Development.vmsd file, shows in Ex in zip as zero bytes, PA restored it as 467K.

                                              Trying a restore using Ex …

                                                  Copied vmsd from Explorer restore to PA restore, VM loads ok.

                                                  Your turn!

                                                      Looks good … restores without a crc, destination file is zero, VM loads.

                                                      Thank you.

                                                        Let us know via email to extend your Select plan (if you dont have one, we will create it for you), this was definitely bug find of the month!

                                                        Pretty tricky, everything was compressed fine but extract did not work on 0 byte files if they were stored after 4 GB position in the zip archive (if they were saved before 4 GB in 100 GB archive it was fine). Thanks a lot once again!

                                                          I could not find an email, so I sent a PM a while ago.

                                                              Why didn’t I think of this post earlier … :(

                                                              Yesterday I needed to restore a VM … restored would not load … dictionary error, so do research, nothing works … :(

                                                              Then I find a file Development.vmsd, which should be zero in size, is restored as 4,294,967,296 bytes … hhmm I remember that :(

                                                              Running PA 16.10.14.

                                                              Rest of info as per the top of this thread :)
