I have an error on one of my client. I get the following error on one of the client that is reporting to a policy manager server : The file C:\Program Files\F-Secure\Common\CommDir\policies\policy.bpf did not pass signature verification.

    I am not sure why this issue has been tagged as it has given a solution. I guess I have to call you guys regarding this directly.

    Isn't there a solution to this? 

    This occurs to me as well. I have successfully installed hundreds of clients, but with a couple of clients i have recieved this message.

    Oh, and i have not reinstalled PCM.

    Hello Anden,


    Still, the most probable issue is wrong on the client.

    So, I would propose to uninstall the product on problematic hosts using uninstalation tool:

    In addition, please, delete



    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Data Fellows

    registry (differs for 32-bit and 64-bit OS),

    and make sure that you don't have any file in F-Secure and/or Windows/User(s) temp folders.

    After that repeat the installation providing correct (push installation from PMC or MSI is best).


    Best regards,
