ArcGIS deauthorization error

[JurisZarins]

Problem with deauthorization of concurrent use license. For limited time i need license on another computer (at home) and make authorizarion (not borowing) from license server (at work). When later try to deauthorize get error "Error returning fulfillment (FID-1415296154) to license server ... ".  Any suggestions please.

Contact Esri support, they can reset the license.

(Excerpt from my internal KB)

[...] Each time there was a message "Error returning fulfillment (FID-999...) to license server (SERVER)", where "SERVER" refers to a machine that no longer exists. Afterwards the total license counts for all products on this LM were wrong. Some higher, others lower. Our corporate license admin (Ryan Gould) supplied a recipe that fully resolved the issue.

REPAIR CORRUPT LICENSE AUTHORIZATION

Delete the licensing trusted storage:

• After deauthorizing your Concurrent Use licenses, stop the ArcGIS License Manager Service and close ArcGIS License Server Administrator.
• In Windows File Explorer, navigate to the following directory: C:\ProgramData\FLEXnet
• Delete all ArcGIS related files from the FLEXNet folder (or if there are only ArcGIS related files, you can simply delete the FLEXNet folder).
• Return to the ArcGIS License Server Administrator and re-authorize your Concurrent Use licenses (including 3D Analyst).
• Verify the details in the Availability folder and in the diagnostic report from the License Manager. You might need to “Start/Stop License Server >> Re-read Licenses” to correct Availability.
