I have a new computer system with Windows Vista. I was trying to load my son's iPod and iTunes on it when it indicated I needed to install QuikTime. I downloaded QuikTime and went to install it when I got the error number 2739 - installation of QuikTime did not install succesfully. What can I do to get QuikTime installed sucessfully? I have a 17 year old that is driving me nuts because he can't sync his iPod now. Thanks.
