It's just a guess, but it might have been related to pathing.
When I run it manually it uses the pathing established with my log in.
To get the app to run as a service, I had to change all the network drive letters in the app.config to their natural equivalents.
The app might still have been looking for the report viewer on a network path.
Including the report viewer in the app avoided that issue, if it was one.
