Symptoms

Cannot open FlexiCapture 12 applications, receiving the error:

Cause

Not all components are configured correctly, or servers with FlexiCapture 12 components cannot reach each other.

Resolution

1. Make sure that the Licensing Service is running on the server.
   
   • Go to Control Panel → Administrative Tools → Services;
   • Select necessary Licensing Service:  Licensing Service or ABBYY FlexiCapture 12 – Licensing Service;
   • Press “Stop the service” and then “Restart the service”. 
2. Check if all settings for the Licensing Service are correct (see “Help → Distribution → Activating the Library → Installing Licensing Service”). Try to set or change the port number in the network settings of the LicensingSettings.xml both for the server station and for the workstation manually:
   
   1. Change LicensingSettings.xml for Server:<?xml version="1.0" encoding="utf-16"?>

      <LicensingSettings xmlns="http://www.abbyy.com/Protection/LicensingSettings">
      <LocalLicenseServer>
      <ConnectionProtocol ProtocolType="TCP/IP" EndPointName="3020" />
      <EnableIKeyLicenses Enable="no" />  "no" - if you use software license, "yes" - if you use USB protection key
      </LocalLicenseServer>
      </LicensingSettings>

   2. Change LicensingSettings.xml for WorkStation:

      <?xml version="1.0" encoding="utf-16"?>
      <LicensingSettings xmlns="http://www.abbyy.com/Protection/LicensingSettings"><LicensingServers>
      <MainNetworkLicenseServer ServerAddress="127.0.0.1" ProtocolType="TCP/IP" EndPointName="3020" />
      </LicensingServers>
      </LicensingSettings> 

3. Nothing like closed ports or insufficient user rights prevents Licensing Service’s appropriate work. Check if the 3020 port number is opened from the server station to the client workstation:
   

   1. Check if you have the telnet installation on the workstation:

      • Pass to Control Panel → Programs and Features.
      • Press the «Turn Windows features on or off» on the left menu.
      • Select the «Telnet Client» checkbox in the Windows Features dialog box.
      • Press the «OK» button.

   2. Open the command line on the workstation and launch the following command: telnet 127.0.0.1 3020.

      • If there occurs the error message «Could not open a connection to the host, on port 3020: Connect failed» in the command line, therefore, the port 3020 is closed on the server station.
      • If there occurs the empty console, therefore, the port 3020 is opened and available on the server station.
4. Probably the FlexiCapture 12 and License Service are from the different distribution packages? If yes, try to reinstall FC on the computer, where you receive the error message “RPC-Server is unavailable”.
