		# CMake didn't set the install scope properly. They "fixed" this in
		# version 3.29. Unfortunately, this causes the installer to no longer
		# be compatible with previous installs, leading to updates becoming
		# impossible! It'll check if the application is already installed,
		# notice that the existing install is per-user while the new one is
		# per-machine and then MSI in all its wisdom will just install the
		# application halfway a second time and not replace any files, leading
		# to the user having multiple desktop shortcuts and start menu entries
		# and aaargh it hurts. I don't know if there's a way around this, but
		# for now, we're reverting to the old, now-deprecated behavior, because
		# that actually works. Yeah it won't create start menu shortcuts
		# properly if you have multiple users on your machine, but that's such
		# a niche use case that supporting it really doesn't matter. See
