Signature check failed on all computers.



All of computers in policy manager console reports “signature check failed (…) policy.bpf did not pass signature verification. The file may have been manually modified. If the problem persists, please contact the system administrator.”

Is there a chance to renew admin and hosts keys, to resolve this problem?


I reinstall one of the hosts with with it's own policy (export and import policy) but, after I did that it do not block  USB devices. It unblock all devices. Is there a chance to import device control settings somehow?

    Did you do a new installation of PM or why did the keys change??
    Do you have a copy of the old H2DB?


  • Previous IT technican left me this problem, so i don't know.

    Probably he reinstall Policy mangager or upgrade it.

    Control Panel shows that it was installed on january 2016 version 12.00 build 67239.


    There is no copy of H2DB.

  • Hello,


    You're awesome. After replacing it works like a charm and hosts have latest policy.
