After some debugging, i found that procgov calls a function that’s incorrectly implemented in wine-win32.
7z extracts just fine.
And if procgov is not found, Navigraph Hub will invoke 7za.exe directly, so the workaround is simply install Navigraph Hub then delete /steamapps/compatdata/1250410/pfx/drive_c/users/steamuser/AppData/Local/Programs/navigraph-hub/resources/assets/bin/procgov.exe, then install won’t fail anymore.
