+ <!-- Schedule the upgrade to afterInstallExecute means that MSI will first install the new version
+ over the existing version and run the uninstall of the old version afterwards. This way shortcuts
+ are not recreated on every new installation and pinned shortcuts stay alive.
+ However this requires that the components for installed files with the same filename will always
+ have the same GUID (do not run heat.exe with -gg flag) or else when MSI removes the components
+ of the old version with the same filename as components of the new version it will delete the
+ files that belong to components of the new version.-->
