That might work. Especially since TechDragon mentioned in another thread he had tried something called "wine-doors", not something I'm really familiar with, but it sounds like one of those scripts/apps that will overwrite your wine configuration files.
Also have you tried this from the CLI? If so, what was the output?
Make sure you are running this as a regular user, not root.
