I have no idea what's going on here, but I just want to report my own experience. I have BW 9 installed on a Windows 7 Pro 64-bit computer. I had no problem with the installation. The help videos run fine. I'm not sure whether I have Macromedia Flash on the computer. It does not appear in the Windows Uninstall list of programs, but there are two entries for Adobe Flash Player 12, one ActiveX and one Plugin; perhaps that's it.
Brainout, I can't begin to offer a solution to your problem, but clearly it is not widespread at all, or other users would have been hollering too. Is it possible that your BW 9 installation disk is defective?
