I'm unable to install itunes on my laptop. It had itunes earlier ver & i've the same setup file but whenever, i try to install it, it doesn't install quicktime properly.

i have removed quicktime from my laptop & tried to install it again but no luck. Everything is working perfect but just because of quicktime, itunes is also screwed up.

The only reason I want it is to sync iphone with it.

Kindly help.
BTW, I've also tried method of removing all quicktime files from registry but still no luck.
