Different version PYTHONPATH env variable interferes with NX CAM simulation application
Solution
NX application is accessing Python 3.6Version located inside NX Install Dir.
The solution is while start in from a batch script to unset the variable PYTHONPATH, so it will stay on the system not removed, but for the application NX it will be unset and so NX CAM Simulation will no longer have problems and find the correct python 3.6 version.
Please create a new batch file with below contents and save it as *.bat and launch NX by using this bat file to use dedicated Python2.5.
set PYTHONPATH= "Your Python2.5 install Dir"
NX Install Dir\NXBIN\ugraf.exe (NX install dir.)
