Hi Don,
Did you install the application as admin? If not then please install it as admin.
Can you clear the cache (type %appdata% in the address bar), rename the Ansys folder to Ansys.old, (type %temp% in the address bar).ansys folder to .ansys.old, and relaunch the application.
Also, can you check your event logs goto START--> event viewer--> expand windows logs--> select Application log. Do you see an error logged over there?
