Hi,
Thanks for the info. It sounds like you are running on a Mac? If so, did you originally install from the Mac Apple Store or from autodesk.com for your account? And was the location the students installed from the same? I'm wondering if you installed from one location and they installed from another?
Also, you mentioned some systems are running Drawings fine. Are these systems the same as the one with problems? Were they all installed from the same source as you?
If you're using the AppStore version, I wonder if you're account is an admin account and theirs are standard users? It may be that when they try to run the Drawings it's trying to access files their accounts don't have rights to? Or if the Drawings module is trying to access files in your account's folder structure they can't.
If you want to run Fusion for multiple users you will need to install it globally using the admin account. If you wnat to run it locally (the default) then the other accounts on the system will require admin access rights.
Thanks for your patience as we try to figure out what's going on.
