    What is Exception code: 0xc0000409?

    Actually, Dave, I'd just like to know what this code denotes. Exceptions are usually thrown because of a memory segment violation. Is there a table somewhere documenting error codes and what they mean? ...Probably in the SDK, but how about for users?

    I ask in order to determine whether a bug report should go to Microsoft or to NVIDIA.

    An exception, Exception code: 0xc0000409, is thrown during a device driver install failure.

    PS: The exception is 100% repeatable.
