Using CCS 6.0.0.00190 with a full license, with the license file in a non-default location, I have noticed that after performing an update to CCS that when re-started CCS drops back to either "Unlicensed" or "Free License". To get back to a full license have to go to Help -> Code Composer Studio Licensing Information -> Manage -> Add and re-point to the location of the full license file.
The same issue has been seen under Linux and Windows.
This is a minor issue, since only happens after a CCS update, but is it correct that an update causes CCS to "forget" the location of the license file?
