Error 000819: The tool is not available or is unassigned

[ErnejunCorvera]

I tried to create workflow database using Create Workflow Database tool but returns an error 000819. I have an advance(personal) desktop license with ArcGIS workflow manager installed.

Did you turn on the extension for Workflow Manager (Customize > Extensions)?

[ErnejunCorvera]

yes, extension is on both arcmap and arccatalog.

Not sure if it will work but worth a try.

Open ArcCatalog > open ArcToolBox > (If WorkFlow Manager Tools is not available, add it to ArcToolBox).

Repeat/Check the same for ArcMap.

I finally solved the problem by disabling Background Processing from Geoprocessing option....

Make sure to make this as answered so it can be closed.

Me to. Disabling the background processing resolved the problem.
