Error 1067 when attempting to install a windows service application

I'm attempting to install a windows service application i completed. This runs fine in debug mode calling onstart(null) just fine, but when removing debug code and attempting to install this as a system service im' greeted with the error:

Windows could not start the "name" service on local computer.

Error 1067: The process terminated unexpectedly.

Any ideas here? Any help is much appreciated!

In event viewer i am given this callstack:

I have tried many things, including forcing a full uninstall of the application and cleanup of the registry service tree, reboot and re-installation. I even tried starting the app from powershell to see the output which didn't provide me with much either.

Any help is appreciated.
