I've repaired and reinstalled the installation a few times but when this user goes to use the software it still has the same problem on his account. When though it worked fine on mine. Now this is were it gets weird for me, after we switch to his account and Solidworks crashes on loading parts/creating new parts; I'll switch back to my account and the Solid Works (Which was working fine before we switched to his profile) is now no longer working on my account with the same issue.

Any ideas on what could be causing this?
