When submitting a command request from the command-line scanner, you may get an error message that a valid license is not installed.
You may also see this similar error from Protection for SharePoint Servers:
"An error was detected during the scanning process. Error:558. Aborted - No scanning license. Please contact your administrator to verify this message."
This can be caused by having a feature enabled that is not included in the license currently installed.
You can also view this information in the report.xml:
When Protection Engine was installed, there was an option provided to enable URL filtering and reputation. If these were enabled, you must go in to Policies -> Filtering and disable it under the URL tab:
In order to disable this feature from the command-line, change directory to the Protection Engine installation directory and run these commands:
xmlmodifier -s //filtering/URLFilter/@enabled false filtering.xml
xmlmodifier -s //filtering/URLReputation/@enabled false filtering.xml
