Products Effected:  DentalCAM 6, DentalCAM 7

Symptom:  Upon STL file selection, "Run-time error 70" appears and DentalCAM closes

Details:  Selected STL has read only or limited file permissions for current user

Solution 1: Copy STL file to local drive (e.g. if STL is on a server), restart DentalCAM, try to re-nest STL file again

Solution 2: Verify STL file does not have "read-only" access rights (see below screenshot) 

Solution 2a:  Verify DentalCAM installation path does not have "read-only" access rights (e.g. C:\vhf\DentalCAM_7\)
