After following the steps described in System Administrator`s Guide for protocol change to TCP\IP there is still an error: The RPC server is unavailable.

In order to fix the issue, please use the instruction below to change to protocol type to TCP/IP:

1. Install Server and License Manager.
2. On the Server open the file %programfiles%\Common Files\ABBYY\FineReader\14.00\Licensing\Licensing.ini and enable here TCP/IP protocol and 81 port:

   [Licensing]
   ConnectionProtocolType=TCP\IP
   ConnectionEndpointName=81 

3. Open the file %programfiles%\Common Files\ABBYY\FineReader\14.00\Licensing\NetworkLicenseServer.ini and enable here TCP/IP protocol and 81 port:

   [Licensing]
   NetworkServer=yes

   ConnectionEndpointName=81

4. Copy the file Licensing.ini with the changes to %programfiles%\ABBYY FineReader 14 License Server.
