A customer complained that Autoplay was not working when he inserted a CD. I manage to get that function back, but now when he double clicks the desktop shortcut or the icon in Windows Explorer he gets the error: "Windows cannot access the specified device, path or file. You may not have appropriate permissions to access this item."
If he opens Windows Media Player, the audio works.
The OS is Windows 7 Ultimate.
What do we have to do to get Autoplay to work correctly?
