I would like to use draftsight free (2015 x64) in a restricted user account, but it does not work.

In the admin account, everything is fine. If I try to start it in the "restricted user account", I get the message that "I cannot access the file. I have no rights..." (or similar - it is a message in german, so I don't know how it exactly translates).

Is there a way to use it in such an account?

thank you in advance!
