Regedit and wine regedit do NOTHING in terminal

and

i'm installing WOW right now, and it keeps trying to install gecko, i click install, and it looks like it installs, but does nothing. Each time i do an update, it asks the same thing over again. I looked around for a way to manual instal, but the one that was written for feisty does not seem to work for me.

step 3 does not work for me for some reason.. here's the terminal output:

stephan at stephan-desktop:~$ mv wine_gecko ~/.wine/drive_c/windows/gecko/0.1.0/
mv: cannot stat `wine_gecko': No such file or directory
stephan at stephan-desktop:~$ mkdir -p ~/.wine/drive_c/windows/gecko/0.1.0/
stephan at stephan-desktop:~$ mv wine_gecko ~/.wine/drive_c/windows/gecko/0.1.0/
mv: cannot stat `wine_gecko': No such file or directory
stephan at stephan-desktop:~$ 


please help on both counts   :)
