Query: It doesn't work on Vista

After installing it on Windows Vista and rebooting to system, it stopped working. I repeated the process several times and never got it to work. I tried it in another computer working on Vista and couldn't even complete the installation. Even the most recent version of the driver didn't solve the problem. I installed it on Windows XP and worked just fine. Video quality is good and works with both GMAIL and SKYPE.
