Worker Agent fails to start

Version: Windchill 12.1

Use Case: I am setting up a test server for Windchill 12.1.2 wit Creo 9.0.8 and CreoView Adapter 9.1.0.0.

Description:

In Worker Agent Administration, I get a greyed out start flag for the worker and using the Start All flag, it returns Fails to Start for the server. If I go to the Adapter folder, I can manually start proeworker.bat and then I can start the worker in WAA.
Auth.properties and agent.ini are set right, as compared to my 12.0.2 production system which works fine.
In WVS.properties, I have set worker.exe.whitelist.prefixes=E\:\\PTC\\creo_view_adapters_91. This matches what I see when I look at the folder in windows explorer.
Are there any other files that control publishing that I have missed?
