Installer works, but there are a few issues with it.
- It doesn't register the DesktopBackground COM server
- It doesn't create a start menu shortcut with the AUMID
- It doesn't check for .Net Framework 4.8 or later
- It doesn't try to install .Net Framework 4.8 or later if not there
- It doesn't have any customised backgrounds...
- It doesn't ask to run DisplayMagician when install is finished
