The "RPC-Server is unavailable" message usually appears when the Engine installation is configured incorrectly or something is wrong with the settings of the Engine-based application.
Сheck the following:
1) The Licensing Service is running on the server.
- Go to Control Panel → Administrative Tools → Services;
- Select necessary Licensing Service: ABBYY FineReader Engine – Licensing Service or ABBYY FlexiCapture Engine – Licensing Service;
- Press “Stop the service” and then “Restart the service”.
2) 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:
- 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="3000" />
<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="3000" />
</LicensingServers>
</LicensingSettings>
3) Nothing like closed ports or insufficient user rights prevents Licensing Service’s appropriate work. Check if the 3000 port number is opened from the server station for 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 3000.
- If you receive the error message «Could not open connection to the host, on port 3000: Connect failed» in the command line, therefore, the port 3000 is closed on the server station.
- If you receive the empty console, therefore, the port 3000 is opened and available on the server station.
- If it doesn’t help please describe the command «telnet 10.160.50.15 3000» results and send to technical support.
4) Probably you use ABBYY FineReader/FlexiCapture Engine and License Service from the different distribution package? If yes try to reinstall FREngine or FCEngine on the computer, where you receive the error message “RPC-Server is unavailable”.
In case none of the mentioned recommendations were helpful, please send to technical support the following additional information:
- The AInfo report collected from the problem computer. The report (a ZIP file) can be created by the AInfo utility (run Ainfo.exe from the \Bin\Support folder of FREngine).
- Is the Engine license visible in the LicenseManager window? Please make a screenshot of LicenseManager window and send it to us.
- Please send us a screenshot of the lists of running services where ABBYY FineReader Engine. Licensing Service can be seen, together with it Status and Log On As.
