The MSI gets a setup wizard (WixUI dialogs, no licence or folder page) with a
Shortcuts page: the Start Menu shortcut as before, plus an opt-in "Create a
desktop shortcut" checkbox bound to DESKTOPSHORTCUT. Silent installs take
DESKTOPSHORTCUT=1. The shortcut goes on the all-users desktop (per-machine
install) in its own component with an HKCU key path (ICE38/43/57), so
uninstall removes it; upgrades read that value back and keep the previous
choice unless DESKTOPSHORTCUT is given.
The build now needs WixToolset.UI.wixext 5.0.2 (release workflow and
package.ps1 updated).
