Windows installer regression in Nightlies (Workaround included)

[Asinin3]

As reported in Discord, LANraragi's Windows MSI installer regressed and now gives the following error:

This prevents the application from installing properly. However you can close the installer once it's done and go to
C:\Users\Someone\AppData\Roaming\LANraragi and run DistroInstaller.exe this will fix up the installation.

I'm pretty certain it regressed from one of the commits in this PR #640

I've been aware of this issue for a little while but don't have a clear reproduction state yet! (it doesn't happen on my rig which is annoying).
I want to fix it for 0.8.6 however so:

• Does this happen on clean installs, upgrades or both?
• Can you get a verbose log through msiexec so we can see what the cli command that launches distroinstaller during the installation process looks like?

Sorry for the annoying questions but help would be much appreciated! 👍

Happens on clean installs, haven't been able to test upgrades as I dont have a newer/older nightly build and the nightly page only has the latest build for download

Been making progress on fixing this -- In the meantime, I've also added a shortcut to run DistroInstaller in case the installation is incomplete, which should help in other fringe distro-not-available scenarios.
