vRealize for Horizon/Published Applications binary file signature expired (2147906)

  • 3 Ratings


  • The broker agent service cannot startup correctly and the v4v_brokeragent_svc*.log shows errors similar to:

    Assembly v4v_viewapiconnector.dll is not TRUSTED, hence aborting

  • The broker agent configuration utility cannot be opened. A Microsoft .NET Framework error is reported:

    Just-in-time (JIT) debugging instead of this dialog box.

    ************** Exception Text **************
    System.NullReferenceException: Object reference not set to an instance of an object.

  • The digital signature of a V4H or V4PA binary file expired.
  • The digital signature of the binary file contains a SHA1 signature, but no SHA256 signature.


The broker agent cannot load the DLL during startup because the binary file's VMware certificate expired on 11/16/2016, and it is not trusted. In addition, Microsoft changed it's certificate signature verification on 01/01/2016.

The SHA-1 algorithm is deprecated and Windows will not trust a certificate signed by a SHA-1 signature. Before 01/01/2017, the SHA-1 timestamp signature is still working until its expiration.


To resolve this issue:
  • For a 6.1 broker agent, upgrade to a later release.
  • For 6.2 and later releases, install the patch release of the broker agent available at VMware Downloads.
