Need help! Something went wrong in iTunes install

Question

During my install of iTunes 7, my laptop overheated and shut down. Now when I try to install itunes it tells me that quicktime.msi is missing and the old copy of quicktime can not be replaced. It won't allow me to uninstall the old version of quicktime and I can't even open iTunes without the new Quicktime. Does anyone have any ideas how to fix this issue?

Now when I try to install itunes it tells me that quicktime.msi is missing and the old copy of quicktime can not be replaced. It won't allow me to uninstall the old version of quicktime and I can't even open iTunes without the new Quicktime.
let's try this first.
Download and install the Windows Installer CleanUp utility. then use it to clear any existing QuickTime installation configuration information from your PC:

Next, we’ll manually remove leftover program files and folders.
1. On the Start menu, click My Computer (or double-click My Computer on the Desktop).
2. In My Computer, open Local Disk.
3. Open Program Files.
4. Right-click on the QuickTime folder and click Delete from the shortcut menu.
5. Navigate to C:\Windows\system32\.
6. Remove the files QuickTime.qts and QuicktimeVR.qtx.
7. Restart your computer.
once we've got all the existing QuickTime scraped away, let's try a careful standalone QT 7.1.3 reinstall.
download and save a copy of the QT 7.1.3 standalone installer to your hard drive. (we'll run the install from there rather than online.) switch off antivirus and antispyware applications prior to the install.
Quicktime 7.1.3 Installers … get the one that doesn’t mention itunes
if that install goes through okay, does an itunes install go through okay afterwards?
(if you get an error message on the QT standalone reinstall, let us know what it says. include error message numbers if you're getting any.)
