Hi Wess Gates
I had to change a *.STP file i had to actually be .step and when double clicked it it asked what program and i navigated prgroam filesansysv201scdm and picked the same exe i load SC with.
If you load the same Spaceclaim.exe do get the server error?
What if you doubleclick an scdoc?
Do you have multiple SpaceClaims installed?
