I don't know you added that .txt it should not be there... go to http://wiki.winehq.org/winetricks, open your terminal and type the command in. Winetricks will be in your home folder (/home/username/) now don't touch it in anyway, in your terminal type sh winetricks ie6 you'll get an output of something downloading once it finishes it will automatically ask you if you want to install just click yes and let it finish then you're done.
