Uninstall any installed drivers\software for the camera. Log on to the scanner manufacturer website and update the latest driver\software for the device and check if it helps.
If you are still unable to start the “Windows Image Acquisition” service, perform a system file check for any system file corruptions. To do so, follow these steps.
Click Start, All programs and then Accessories. Click Command Prompt.
In the Command Prompt window type “sfc /scannow” (without quotes) and then press Enter.
After the scan has completed, close the command prompt window, restart the computer and check for the issue.
