Workaround for an issue after upgrading from WiX Toolset v3 to v5 where the previous version of Dangerzone is not uninstalled during the upgrade by checking if the older installation exists in "C:\Program Files (x86)\Dangerzone". Also handle a special case for Dangerzone 0.8.0 which allows choosing the install location during install by checking if the registry key for it exists. Note that this seems to allow installing Dangerzone 0.8.0 after installing Dangerzone from this branch. In this case the installer errors until Dangerzone 0.8.0 is uninstalled again
