    Just wondering if there's a 64-bit version of 7za.exe? Can't seem to find it in:

    http://www.7-zip.org/download.html

    Thanks!

      I don't upload that file.
      Why do you need it?
      7z.exe + 7z.dll provides same features.

        @Igor

        I'm using 7za.exe with the nsis installer.

        I just use it for extract file in the .7Z archive.

        On the download page of the site, I see this 7za.exe for 32-bit of windows version only.

        is this 32-bit 7za.exe work on windows 64 bits systems ?

        thanks
        sorry for my bad english :(

      Hi Igor,

      Thanks for you reply!

      I'm using the following command to do a daily archive of multiple folders on various servers (primarily x64).

      7za a -t7z -r -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on archive.7z @backup.txt
      (with @backup.txt being a list of folders to be archived)

      Does that mean that I can simply replace the above command with the x64 version of 7z.exe (and copy 7z.exe and 7z.dll to %windir%\system32)?
      i.e.

      7z a -t7z -r -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on archive.7z @backup.txt

      Thanks!

    Still looking for x64 7za. To the question of why I need it, WinPE does not include a 32 bit subsystem, so only native x64 binaries will run on it.
