[Wine] Can't uninstall software

[GeoffAk]

Hello.  I am using Ubuntu 10.10.  I am trying to reinstall "Sonos Desktop Controller" and can't seem to do so. When I click "Remove" in Add/Remove Programs the screen simply flashes and the program is still there...nothing happens. I've tried removing the directory in "~/.wine/drive_c/Program Files/..." and the GNOME menu items, but the program still won't reinstall (I'm trying to install a newer version).  I'm guessing there are still Registry entries that need to be removed, but I'm not sure.  Any ideas?
