We had to uninstall quicktime. Example at http://pabsungenis.livejournal.com/94683.html
I have been trying to install itunes on my PC. PIV 2.6 Ghz 512RAM OS XP with SP2 installed. Initially I was getting a message saying msiexec.exe has encountered a problem and it is shutting down. That problem has been solved (Details are at http://forums.windowsforum.org/index.php?showtopic=28514) and now the installation goes beyond this screen. When it starts installing Quicktime which is required for itunes I got a message saying "'the installation of Quicktime did not complete successfully. Itunes require Quicktime'" After pressing Ok it came to the last page where in it said that the iTunes installation could not be successfully completed and was asked to press Finish.
How do I sort out this problem? Thanx in advance
