    Hi Keito,

    The Could not open KSP key: -2146893802 error refers to the Verba API certificate, the most likely problem is that the certificate's private key is not exportable. If you run into this issue in the future, please open a ticket at

  • Hi Daniel,

    This is very tricky issue and we found workaround.  If we install the system on the OS without Windows update, Verba Web Application Service runs properly without error. But service always fails if we install the system on the OS which already applied Windows update. 

    The issue is nothing to do with platform is on the physical server or VM. It must be related something included in Windows update.

    Best regards,
