Note; I've just Wine with Windows 7 and RollerCoaster Tycoon 3 Delux and Thunderbird 2.x installed - nothing else -.
What? Are you trying to use Wine under Windows 7 or are you running Wine under Linux?
Wine 1.0.1 does not have an option for Windows 7 mode. So what version are you using?
Try again in the latest Wine, if the problem persists, attach the console output. http://wiki.winehq.org/FAQ#get_log
