Hi, it's very simple, if this a process that is required you explain this and have each user set a link in his / her startup folder so that it startup when they login.
It's just a question explaining.
If it's on a network you can ask the network guy to place this in the user's startup script.
All tasks and work procedures start and end with the users complying with the stated policies.
Train the users and you'll probably succeed, if they see the need and advantage, who knows ...
