It is possible to have parallel installs with a workaround. Just copy the the cubase folder in program files before the update. Call it cubase 9.30 or whatever version it is. It will work from that folder. You can even place the folders on other drives if you want to. If you don’t like the 9.41 just delete it and rename your backup folder back to what it was. It is an at your own risk method and there might come a point it fails, but it worked here with an older version.
