Fix-  You must click SAVE AND PUBLISH to make the model active. Simply open your model in AI Document Center, click the PUBLISH button, and the RUN EXTRACTION button will appear. Only published models can be tested.

The model should be published before Run Extraction button is enabled. So first publish then try!
