Symptom:

System error email notifications are going to the wrong email address. How Do I change that?

Resolution:

Here is the default path on the server:

Program Files\Metafuse\Project Insight\Windows Service\ProjectInsight.WindowsService.exe.config

Open that file with note-pad and edit the email address in this string:

<add key="ErrorEmailAddress" value="projectinsight.windowsservice.errors@metafuse.com"

If you want to add multiple email addresses, they can be separated by semi-colons.
