I have multiple standalone licenses that are activated on different computers. Is there a way to tell what license is on each computer? I did a quick search of the registry and do not know what filename or folder the info would be in.

Yes, if you have not kept a record of license association with user system, you can report the user / support ID number you see at the CMS IntelliCAD HELP menu > About IntelliCAD box.
