Testing this PR on windows, #31 is fixed but there's a new issue, extract_assets.bat doesn't get executed & trying to open any of the games through the launcher results in this error.

Manually executing it resolves the issue.

Hello, after trying to build stephini's launcher and failing, I found yours via the pull requests and wanted to say thank you for this. I also submitted a pull request to them with newer python modules in the requirements for building against a slightly more modern python person. Are you more active than they are?
