To clarify, those text files are located in this directory? (or whichever version of NX you're using)
C:\Program Files\Siemens\NX 9.0\UGII
I added in the text to both files and re-opened the program, but no luck.
Tutorial on setting environment variables:
Variable name: EDITOR
Variable value: C:\Program Files (x86)\Notepad++\notepad++.exe
Variable values needs to be set without quotes.
but if you edit to an external editor and then save nothing change, only way is to Copy from external editor and paste in Post Processor Builder?
