When you are running the Diagnostics Console on a machine that does not have the Diagnostics Service installed, the following error may be logged in the Error Viewer:
Unable to read Hyland diagnostics registry key value.
This error is displayed if the Log Profile value is absent from the registry and you are using the Diagnostics Console to monitor an application that is not .NET-based. When the Log Profile value is absent, the Diagnostics Console can still be used to monitor errors generated by the application, but it cannot be used to monitor database calls, disk group access, and other types of messages.
To resolve this issue, create the Log Profile value in the registry.
Modify the registry at your own risk. Incorrectly editing the Windows registry can cause serious problems that may require you to reinstall your operating system. Be sure to back up the registry before making any changes to it.
