Description: This error appears when attempting to scan or select a scanner inside the Eclipse UI or capture tab inside the client.
Software Version: All Eclipse versions. Notably with Canon scanners.
Solution: There are several fixes for this error.
1. Attempt a full pixtran reinstall of scanner drivers. Renamed pixtran folder, delete loose files, uninstall scanner. Restart computer and reinstall client and drivers.
2. Disable the EMC Captiva Cloud Service. Canon has known issues with this service that installs as part of the driver package.
3. Disable the Windows Image Acquisition (WIA) service. Windows software can conflict with Eclipse and hang up the drivers.
