* Chosen images on the TE appliance are all downloaded successfully and ready.

## Cause

   The agent sends a request to the TE appliance to emulate a file on an image that does not exist on the appliance causing the error.  

2. ICAP server was enabled and configured with mismatching Images (for example, WIN10 image) and not the Recommended ones.
