according to the CCSv5 FAQ page:
Yes for any beta version before RC1. Just copy the file into ccsv5\ccs_base\DebugServer\license For RC1 and after please download the temporary license along with CCS (available from the same download page) or purchase a v5 license when they become available in the very near future. V4 licenses under subscription will be able to obtain a v5 license
so i copied my .lic file into that directory and chose to activate it in CCSv5.1 but it says it is for CCSv4 and i cannot debug. i do not see any "temporary license" on the download page so maybe that is the piece i am missing. there is almost no documentation on this. is this possible or do we have to buy CCSv5.1 licenses?
