I can't activate my license. I enter my serial product for CS4 butafter, it ask me the serial number of a previous version for an other Adobe product.
I don't understand why i can't activate my product just with my serial number.
Somebody can help me please ?
It is because your version of CS4 is an upgrade version that you paid a lower price to obtain. You need to provide proof that you own an earlier version in order to use an upgrade version. This is done by identifying the older version and providing its serial number.
Error "This serial number is not for a qualifying product" | CS6, CS5.5, CS5
