A few days ago I upgrade my workstation to Win7 Ultimate x64. When I tried to open Flash Builder beta2, my license had expired (I had 57 days left!). I tried re-installing, but as expected, the license was still expired. Is there some public work-around for this?
For Beta 2 (assuming you're using beta 2), we included a License Repair tool in the /install-support subfolder of the main installation folder. Try running that tool, and then launch Builder again...fingers crossed...
Thanks! I'll give that a try :-)
