Hey, One of the most attractive features of Parallels 7 is that the FaceTime Camera is finally available on Windows guest machine. However I have problem on this. The FaceTime Camera is not listed as an available camera in any program, and when I check in Device Manager, there's a yellow triangle besides the "FaceTime HD Canera (Built-in)" logo, and the error status is: Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52) I tried to uninstall Parallels tools and then reinstall it, but it still doesn't work. Could anyone help me on this? Thank you!
