Can't re-install D2K

[wymario]

Trying to reinstall Gruntmods Dune 2000 on Windows 10, which I think I deleted instead of properly uninstalling it, but I can't make the executable install it because it thinks I still have the game installed. If I go to uninstall it through System settings then it says it's installed, but because it can't find the uninstaller it won't try to uninstall it. Is there any way around this?
