Running Vista Biz. Installed the current trial version and I can't get the contextual scanner to work. It just says "Cannot execute NOD32.exe" when I try to scan files from the right click menu in explorer. When I hit the On Demand scanner link in the start menu UAC asks me to confirm and I say yes and then it runs fine. But still a no go from the right click. I'm running as an Admin with UAC on.
