I bought an upgrade from CS3 Master Collection (which qualifies for the upgrade) to CS6 Design and Web premium. Upon installation it asks me for the CS3 serial number. I put the CS3 serial number and it gives me an error.
Do I need to deactivate it CS3 Master Collection from my previous PC?
You haven't mentioned the exact error that you get , but I pressume this article can help you.
