7Zip 1603 Error

1603 is a generic error and could be caused by several different things. Check and make sure that a reboot is not pending, that no other Windows Installer based installs (including Windows Update) are running, and that a newer version of 7zip is not installed.

The code doing the install is here: retcode = subprocess.call(['msiexec', '/qn', '/i', sevenzip_msi_dl_path]) You could try manually installing with the switch /l*v "7z.log" to get more details from the installer.

Run cmdline as admin may help. Reason for code 1603 from https://docs.microsoft.com/en-us/troubleshoot/windows-server/application-management/msi-installation-error-1603.
