Thank you for updating the installation script @zimeg :hero

Any way we could add CI tests for this script somehow? 🤔

@cchensh @WilliamBergamin @srtaalej Thanks so much for the quick reviews 🙏 ✨

Any way we could add CI tests for this script somehow?

Before merging this, I'll look into adding a few Windows tests to this PR. Thank you for calling this out - it's still not clear to me when this started to fail without such! 👾

🤖 issue: Windows in CI is difficult to test I'm finding... I reverted the testing attempts in this PR and find that these scripts work on a personal machine so I'll merge this.

🗣️ ramble: The issue of CI testing isn't clear to me but seems related to updating the path to the installation within the script and with some CI specific settings. I have note to follow up on this if new insights appear!
