What exactly is E:? If anything other than a local device it might not 
be available to the user running the service.

To be clear, the entire Python tree will need those permissions, not 
just that .exe. And the question is whether the user running the service 
has access - SYSTEM and Admin should cover many common scenarios, but 
not all. You could try configuring the service for your specific user 
just to see if it works - if it does it would still point to user 
permissions.
