I later purged brlcad. However I now notice that my wineprefix seems to have been set to: /home/<user>/.wine:/usr/brlcad/bin/dosdevices/ (note the ':' colon after .wine) and I can't seem to change it back to ~/.wine I've checked my .bashrc: export WINEPREFIX=$HOME/.wine my /etc/environment: PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games" Windows registry is also showing brlcad in \Software\Wine\MenuFiles If I delete ~/.wine: and run winetricks, winetricks automatically recreates ~/.wine:/usr/brlcad again. Any ideas how I can rid Wine of /usr/blrcad? (btw: there are no existing brlcad files/folders/directories on the system any longer - including /usr/brlcad)
