I am trying to license Flash Builder 4.6 Premium that came with CS6 Master Collection using the serial number for CS6. I installed CS6 Master Collection and then licensed successfully all products but for Flash Builder 4.6 Premium. When I start Flash Builder, it says it is still in Trial mode. When I try to license it using the serial number that came with CS6, it says that the serial number is invalid.
Please kindly help.
