"FineReader Licensing Service can not be started" error message occurs during the reinstallation


When trying to reinstall FineReader <edition> program on the same machine, the following error messages may appear:

  • ABBYY Licensing Service is unavailable: The RPC server is unavailable.
    Diagnostic Message: 950(0x000006BA) 1050(0x000006BA).
  • The 'ABBYY FineReader <edition> Licensing Service' (ABBYY.Licensing.FineReader.<edition>) can not be started. Please make sure you have sufficient rights to start the service.


The reinstallation issue may occur due to some files from the previous installation, that are still on the machine.

1. Delete the following folders:

  • C:\ProgramData\ABBYY\FineReader\<edition>\Licenses;
  • C:\Users\%username%\AppData\Local\ABBYY\FineReader\<edition>;
  • C:\Users\%username%\AppData\Roaming\ABBYY\FineReader\<edition>;
  • C:\temp\FR<edition>;
  • C:\Program Files (x86)\ABBYY FineReader <edition>.

Note: the Program Data folder may be hidden. To show hidden folders, consult the following link: Show hidden files.

2. Make sure that FineReader Licensing service is not displayed in the registry branch:

If you can see it there, please remove the service via Command Prompt:
sc delete "ABBYY.Licensing.FineReader.15.0"

3. Download the last release of your copy of FineReader: Download links for FineReader PDF 15.

4. Start the installation process by right-clicking on the downloaded file and selecting Run as administrator.

If the issue is still actual, after the steps above, please contact the Support Team.

    • C:\Users\%username%\AppData\Local\ABBYY\FineReader\15;
    • C:\Users\%username%\AppData\Roaming\ABBYY\FineReader\15;
    • C:\temp\FR15;
    • C:\Program Files (x86)\ABBYY FineReader 15.

    Or try the solution described in the following article: https://support.abbyy.com/hc/en-us/articles/360012445419.
