Had similar problems and contacted Orion. Advised to do the following:-
"There have been instances when the device driver wizard will not launch when you plug in the camera but the computer chimes.
1. Open the device Manager.
2. Look for Other Devices on the list of devices.
3. There may be an "Unknown Device" listed under Other devices. This is most likely the camera.
4. Double click on the unknown device (or right click and select properties)
5. Click on the Driver tab.
6. Click on update Driver
Select Browse my computer for driver software and insert CD and click Drivers.
If successful, the camera will appear under the USB serial controllers list and the camera is now installed."
I had to try a couple of time but eventually it worked.
Hope that helps in some way.
