I have a fresh installation of Vista x64 SP1. I installed AnyDVD 18.104.22.168 by right-clicking on it and selecting "Run as Administrator", then restarted the computer when prompted to do so. AnyDVD doesn't work because the driver file anydvd.sys isn't loaded because it isn't digitally signed. I verified this by looking at the device status of my DVD drive. The status is: "This device is working properly. Windows did not start a related device driver. To learn more, click the Driver tab and then click Driver Details." The Driver Details tab indicates that C:\Windows\System32\Drivers\AnyDVD.sys is "Not digitally signed". Any help appreciated.
