@dimesio Yeah. That is the first thing I checked when I saw that error. But...I already have Zenity installed. (According to the Synaptic Package Manager, at least...) @John Drescher (I know someone that has that name. xD) ...that's what I did. I ran "sh winetricks" from the terminal and winetricks opened normally. Then I clicked "install app" and that is when the terminal error messages occur.
