COM problem with Windows Pos Ready 2009 after Windows Update rollout KB4134651 RRS feed

  • Question

  • An ActiveX EXE object exposes a public COM class with events (PippoAux.Connector
    returned as return value of a method, GetConnector, member of another ActiveX COM class of the same component (PippoAux.AppConnector)

    The call from a client to get the class object fails with run-time 430 (interface not found) after Windows Update rollout KB4134651

    Here is the sample code:


    Dim WithEvents pc As PippoAux.Connector

    Private Sub Command1_Click()
    Dim pcloc As Object
    Dim pcc As PippoAux.AppConnector
    Set pcc = New PippoAux.AppConnector
    Set pcloc = pcc.Connect()
    Set pc = pcloc ' HERE ERROR 430
    Set pcc = Nothing
    End Sub


    Uninstalling the hot fix from Control panel, a previous version of oleaut32.dll (8/10/2006) is restored

    In this way the correct behaviour is restored.

    In some cases the uninstallation of the hot fix leaves unchanged oleaut32.dll and the problem still arises.

    Restoring manually the previous DLL fixes the problem too.

    Thanks for your support

  • Please Install the latest update KB4339291 ( July 2018 ) and it should resolve the issue. There were version discrepancy on the dependent dlls and oleaut32 failed to load.

      Please ack. once verified.

  • Hi DamianoFasoli,

    I think this issue was introduced by the below KB/update (KB4074852).


    The KB/Update (KB4134651) with which you are seeing the issue superseded/replaced the update KB4074852.

    Can you please try the below steps and let me know if the issue still exists? I think it will, but please confirm.


    1. Un-install KB4134651

    2. Install KB4074852 from the above catalog location

    3. Check if the issue still exists?

  • Dear Shoeb

    Yes, the problem still arises in this way.

    In fact, with out Hot Line, when KB4134651 was not deployed, we removed KB4074852 to fix the problem, and it succeeded.

    Now the same problem arises with KB4134651  or KB4134651-v2

    l noticed that

    oleaut32.dll 22/4/2018

    oleaut32.dll 6/2018

    oleaut32.dll  8/10/2016
    KB4074852 and KB4134651
    there are no problems

  • Hi Sudheer

    We have tried

    It does not resolve the problem

    This update was also deployed by Windows Update but has not solved the problem

  • Thanks Damiano Fasoli. I think the version of the binary oleaut32.dll (8/10/2016) is 5.1.2600.7149 right? This version corresponds to KB3196718. BTW, there was another KB4018556 that was released after KB3196718 and before KB4074852 that updated the binary oleaut32.dll, can you please check if the KB4018556 has this issue?

  • Hi Shoeb

    Yes, oleaut32.dll (8/10/2016) is 5.1.2600.7149, and with it there are no problems.

    After that, I installed KB4018556, really KB4018556-v2, from here:

    and oleaut32.dll was replaced with the version 5.1.2600.7248 (24/5/2017)

    With it there are no problems too!

    So, maybe problems start from oleaut32 5.1.2600.7424 (6/2/2018) deployed with KB4074852

    Thanks for your support
