It's possible that there are multiple devices listed on your computer which is causing conflict in detecting your scanner. To help you sort this out, follow the steps below:

1. Press Windows key + R, type control then press Enter.
2. On the Control Panel, under view by: select Small icons.

4. Restart your computer.

If the issue persists, create a new administrator account.
