So im trying to install Final Cut Pro 7 on my friends macbook pro with OS 10.6.6 and it keeps giving me an installation error. I suck with macs and ive been reading that since the update FCP doesnt install properly and to get it to work i need to downgrade. I tried follow some guides to do so but it still doesnt install.

Also I am looking for a site to download games for MAC. The game i am looking for in particular is Roller Coaster Tycoon any version i guess. Thanks ahead of time guys.
