I installed FB 4.7 64 bit and entered the serial number on Windows 7 SP1, and all seemed to go fine. But every time I start it up, I get a message saying, "Your application install seems to be damaged, Please reinstall the application." So I finally tried to do so. So I went to Control Panel -> Uninstall or change a program, selected Adobe Flash Builder 4.7 (64 Bit) and clicked Uninstall. Nothing happened. No error message, nothing. I right-clicked on the program name and clicked Uninstall with the same result. I am able to uninstall other software, but not FB. Any ideas?
