How do I disconnect the Icam on

Right click on My Computer and click on PROPERTIES.
Then click on DEVICE MANAGER, and then click on Imaging Devices.
Next click on the + and then on the camera, right click and then click on DISABLE.
Then click on the Red X in the upper LEFT corner.
Then get out of that and install your new camera.
Normal 0 Then make sure to disconnecting the Camera from the USB port and reinstall the software program. When the program asks you to connect the camera to the USB port, do so and it should work.
Hope this helps. Bud
