2 errors in 9.0.2 upgrade

Question

First one - it couldn't find the file iTunes.msi, nor could I find it when I searched my entire drive.
Then it told me that "The older version of iTunes cannot be removed. Contact your technical support group."
So iTunes is dead to rights on my PC.

Answer 1

Then it told me that "The older version of iTunes cannot be removed. Contact your technical support group."
That (and the missing msi message) are consistent with a damaged iTunes.msi on your system, skaks. The iTunes.msi contains the installation database of where all your iTunes program files and registry entries and whatnot are installed. So, the 9.0.2.25 installer isn't able to read that to uninstall the previous version of iTunes, and everything turns to custard.
So we'll have to uninstall your exieting iTunes by other means than by using the Add/Remove Programs control panel. Let's try the following procedure.
Quit iTunes first.
Download and install the Windows Installer CleanUp utility from Microsoft:
http://support.microsoft.com/kb/290301
Now run the utility ("Start > All programs > Windows Install Clean Up"). In the list of programs that shows up in CleanUp, select any iTunes entries and click "Remove". Quit out of CleanUp.
Now go "Start > My Computer".
Open local Disk C: or whichever drive your Program Files are installed on.
Open the "Program Files" folder.
Right-Click the iTunes folder and select "Delete".
Right-Click the iPod folder and select "Delete".
Empty your Recycle Bin.
Now try another iTunes 9.0.2.25 install. Does it go through properly this time?
