You don't need to install it with Lutris per se - as long as the files are already "installed" somewhere on your drive you can set it up in Lutris as a locally-installed game and just use Lutris as a Wine prefix manager. This is largely how I use Lutris - I don't tend to use their installer scripts because I tend to already know how I want the install to go.

I understand that the 8.12 version of Wine is buggy, but by using a manager like Lutris or Bottles you're able to use any Wine version you want in order to run the game, and you could just pick a different Wine version from the list without messing with your system Wine installation. If you don't have time to mess with learning Lutris or Bottles right now that's fair, but they're generally a much better solution for this sort of problem, for now and for the future.
