Scribe EventManager - Error creating the Message Processor

This error came up at a client suddenly. Integrations running fine then one day boom!  Errors (this one) galore.  The exact error is as follows:


System Alert: Scribe EventManager - Error creating the Message Process (Alert # 110, Alert Id 2751)
Access is denied.
(Error code=80070005)


I did some internet searching and it pointed back to DCOM as the cause.  If you open Component Services in Administrative Tools then open Computers > My Computer and DCOM Config you will find the Scribe services listed there along with a  "Message Processor".  The domain account that runs the Scribe services needs to be granted explicit permissions as described on page 5 of the Scribe Insight Installation Guide (version 7.6.1.)


I added the Scribe domain service account and those errors ceased.  That account needs to be added under both Launch and Activation Permission and also Access Permission.
