SKF @ptitude Analyst OPC Manager: recovering from corrupt registry permissions preventing it from changing settings

Summary

The @ptitude Analyst database settings are saved in the registry and if the registry key holding the settings has incorrect or corrupted permissions, then access by @ptitude Analyst OPC Manager may be denied. This would manifest itself by any attempted setting changes not being retained between different sessions of the OPC Manager software and on the startup of the OPC Manager, an error entry being generated in the event log:

MA err: Invalid DB server failed to establish connection to the @A database.

This article describes how to recover from this situation.
