Work around the issue by adding some extra functionality to the "Next" button on the welcome screen of the installer. When the user clicks it to proceed with the installation this: 1. Flips the install scope to "perUser" which is the default in WiX 3 2. Finds the older installation 3. And finally flips the scope back to "perMachine" which is the default in WiX 4 and newer TODO: Revert this once we are reasonably certain there are no affected Dangerzone Installations?
