I recently installed wine so that I could play midtown madness 2 on it but when I installed midtown madness and ran it, it crashed so now I want to uninstall it but I can't is there a way I can get rid of midtown madness? I am running ububtu 12.04.
Wine has an interface for uninstalling software, just run
winecfg. If this doesn't work, you could remove the .wine directory in your home folder, but this will remove any program installed using wine.
I think you should also take a look at playonlinux. It provides you with the possibility to use different wine versions for different programs and easily uninstall software as each program has it's own environment which can be deleted as a whole so you don't have to uninstall any software.
