Well, at least you can get IDCC to start.
I'm running the DX58SO, i920, Win7Pro_64bit, 6G DDR3 RAM and every time I try to start the Desktop Control Center it says the XTU service failed to start. When I attempt to start it manually I get the message that it tried to start but then shut down.
I'm running the latest version of IDCC on a brand new install of Win7. No joy.
