Reinstalling itumes 10

[Guest]

When I try and update to itunes 10 it get quicktime.msi not found and the process stops? why is this? do I need to deinstall itunes 9 first? If I DO deinstall Itunes 9 first, will that also remove all data file eg song and videos. Help please?

Download revo uninstaller. Use that to uninstall itunes. Then download and install the newest version of itunes. You won't lose any data. That is stored in it's own local file. You may need to change the download/source path for your saved downloads.
