Thank you for creating this! We'll try to get it reviewed!

@iso8859 Can you describe what wasn't working for you originally? What actually requires this runtime? (e.g. does the installation itself fail, does it fail to build a project?)

I ask because we tested on a fresh Windows 10 + Windows 11 with all updates installed, and didn't see any issues.

Hi,

This is what you get when you download the installer and run it manually on a fresh Windows 10 machine.

There is no message indicating that the installation has failed when using the powershell script.

In fact, I'm wondering whether it wouldn't be interesting to add an installation success test to the script.

Thank you! We reproduced the issue over here.
