Just a heads up. Soon (hopefully) we will be switching Windows nightly builds to Python 3
Python 3.8+ and above use api that requires a minimum of Windows 8 and can crash attempting to run on Windows 7.
We will not be working around this due to the obsolete and discontinued status of Windows 7 and a check has been added to gracefully refuse to run KiCad in this situation. This check also goes backwards and will reject operation on Vista and XP.
Users are encouraged to switch to any up to date operating system of their choosing.
