Ga Medic, you can go into the registry and delete the Arcsoft KEY, The entire KEY and everything under it.... Then install this cab.... However - one thing that I have noticed that is not functioning correctly is when you view an MMS picture and you click the Menu, then forward, it does not work right... I'm going to IM the guy who made that cab, and we'll see what we can work out to "fix" that issue..... Here's the original post over at XDA for this cab....
