I recently had a total computer failure and had to buy a new one. In the process I have lost Flash Builder 4.5. I have the latest Creative cloud subscription, but Flash Builder 4.5 is not included in the "previous versions" section of apps to install (and 4.5 is the only version that will complete a build of a very old program we are still using).
I have found our old CS5.5 Web Premium installer and installed 4.5 again, but I have no serial number records from back then so I am forced to use it as a trial version for now.
I cannot find anyway to retrieve the serial number for this reinstall, nor activate it using creative cloud.
Any advice?
