Merge e6380f793b into 1d2a91e8c5

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

+Install [.NET SDK](https://dotnet.microsoft.com/en-us/download) version 6 or later. Then, open a terminal and install the latest version of [WiX Toolset .NET tool](https://wixtoolset.org/) **v5** with:
+
+```sh
+dotnet tool install --global wix --version 5.*

+
+Install the WiX UI extension. You may need to open a new terminal in order to use the newly installed `wix` .NET tool:

+
+> [!IMPORTANT]  
+> To avoid compatibility issues, ensure the WiX UI extension version matches the version of the WiX Toolset.
