On Windows, if Python is started with an empty environment (no environment variable at all), Python fails with:

"Fatal Python error: Failed to initialize Windows random API (CryptoGen)"

It's the Windows error 0x80090006 which is not displayed in the error message :-(

In fact, it's because Python 3 cannot be started without SYSTEMROOT environment variable. Otherwise, CryptAcquireContext() is unable to find some DLL.

IMO the script_helper should be fixed to copy the variable.
