The ABBYY FlexiCapture Licensing Service is responsible for making sure that the server is running correctly. Begin by verifying that the service is running:

If the service cannot be launched, try launching it manually with the following command:

The “RPC Service is not available” error

If you see an “RPC Service is not available” message when the program tries to access the Licensing Server, verify that port 3020 is not blocked by your firewall and is not used by any other application (this port is often used by the Common Internet File System, for example). If port 3020 is used by another application, specify a different port:
  1. On the computer where the Licensing Server is installed, open the LicensingSettings.xml file. By default, this file is located in C:\Program Files (x86)\Common Files\ABBYY\FlexiCapture\12.0\Licensing.
  2. In the LicensingSettings.xml file, locate EndPointName="3020" and specify a different port inside the quotes.
  3. Restart the ABBYY FlexiCapture Licensing Service.
After completing steps 1–3, change the port on every computer that accesses the Licensing Server (such as your Processing Server, Processing Stations, Verification Stations, and Project Setup Station). On each computer, open the LicensingSettings.xml file, locate EndPointName, and change its value to the port you selected in step 2.
