Hi, I'm the author of the cmdr2 UI and installer (that iFire linked to). I'd be happy to contribute the 1-click installer used by my project. It's a battle-hardened installer (over 100k installations on all kinds of PCs and networks), and I'm finishing up a rewrite in python, so that the installer code is easier to maintain for others.

I'd be happy to submit a PR to your project, if you're interested in using it. I actually got it working with your project a few weeks ago, so I know it works with your repo.

I've opened a github issue as well, so we can talk there if you'd like: https://github.com/invoke-ai/InvokeAI/issues/1042
