Satsuki Decoder Pack 5.4.2

Maybe I misunderstood but after installing I still couldn't play dvds in WMP 9. Worse yet, I can't uninstall, it doesn't show up in Add/Remove Programs. Advise please.

I used the previous version 2.0.0.6 which was very good, i downloaded the latest version 3.1.0.2 and no more audio languages appear they are greyed i tried to see any hint in the options but unsuccesfully i uninstalled it and re installed the old version ........... need help resolving this problem ? Thanx
