Hey, Here is my situation. We have 3 imacs at our station. We bought 3 Final Cut Studio 3 packages. 2 full versions and one upgrade. Well... I accidentally installed the same full version on two computers. So now two computers have the same serial number which causes problems. The serial number for the upgrade is the one that is available. Ok so i deleted the Final cut studio 3 applications on the one computer. Problem is when i start to reinstall (FCS 3 upgrade) it does NOT ask for the serial number from FCS2. I feel like that is a problem because doesn't that mean its just installing it under the first serial number from the full version? How can i clear any remnants of the full FCS3 i installed earlier?
