I purchased Revit Arch 2011 and have a subscription. I have downloaded Revit Arch 2012 and tried to activate. When I tried to activate, I get a message that my product key was not valid.
Do I use the serial number and product key thhat I got when I purchased 2011. If not, how do get new ones. Do I have to uninstall the 2011 version?
Thanks
