The enhanced gui features need to be enabled for Logic to install. The Qe or CE or whatever its called. I forget atm.
After that you can install and choose to install the library and included logic sounds. Uncheck just about everything though if you only have the logic 8 dvd and none of the apple loops dvd's. The entire thing is 53 gigs.
I use Logic 8, legit along with PTLE 7.4.2 Legit and on a hackintosh, everything works great. My digi002 console is a happy camper.

Next up is my reason 4 and fantom/motif refills.
