ITunes not installing because of Quicktime problem

Question

I just got a 30 GB iPod for Christmas and installed everything on my old computer at home (5 years old but has Windows XP) and everything worked fine. I am now trying to download and install iTunes on my less than 6 month old laptop and am having no luck. With the iTunes setup it gets to Quicktime and then says something is wrong and it can't go any further. I have tried to download Quicktime separately and I get a "2803" error, then a "2350" error. Please help!

Answer 1

Have you tried this:
remove itunes
remove quicktime
remove iPod for windows
remove apple software updater
delete iTunes folder from C:\Program Files
delete quicktime folder form C:\program files
delete ipod folder from C:\Program files
delete apple software updater folder form C:\program files
delete quicktime and quicktimeVR from C:\windows\system 32
delete documents and settings\<user name>\application data\apple computer\
delete documents and settings\all users\application data\ apple computer\
run a search for "quicktime" deleted all files bearing that name.
ran installer clean up (you can get that from (http://support.microsoft.com/default.aspx?scid=kb;en-us;290301)
delete c:\documents and settings\<user name>\local settings\temp
clear temp internet folder
clear C:\windows\temp (Note: Don't delete the folder itself just everything in it)
restart computer
run QuicktimeInstaller.exe from desktop
verify that quicktime is opening
quicktime opens?
If so:
install iTunesSetup.exe from desktop
Verify that iTunes opens?
If you get a corrupt .cab file then the above should fix it. If it still won't open I'd suggest doing an MSCONFIG and then repeating the steps. MSCONFIG can be found here: http://docs.info.apple.com/article.html?artnum=302538
