Python setup problem

deanjennings

Nevermind - I have two KLayout installations. One has the python extensions and the other does not.

~~I have python installed, it's located at 'install path'\lib\python3.7
Ruby scripting works but python produces:
Exception code: 0xc0000005
Program Version: KLayout 0.26.1 (2019-11-14 r595075a8) AMD64~~

~~Backtrace:
