ipod not working after new itunes installed

Hello there, jpbain.

I understand that you're receiving repeated messages that the software was not installed correctly, even after multiple reinstalls of iTunes on your Windows 7 computer. Uninstalling and reinstalling iTunes can be a challenging endeavor and must be done in a very specific fashion. The following Knowledge Base article offers up some in-depth instruction for how to remove and reinstall iTunes in Windows:

Remove and reinstall iTunes and related software components for Windows Vista, Windows 7, or Windows 8 - Apple Support

Remove iTunes as well as its related components from the Control Panel

Use the Control Panel to uninstall iTunes and related software components in the following order:

1. iTunes
2. Apple Software Update
3. Apple Mobile Device Support
4. Bonjour
5. Apple Application Support (iTunes 9 or later). On some systems, iTunes might install two versions of Apple Application Support. This is expected. If both are present, be sure to uninstall both versions.

Don't uninstall these components in a different order, or only uninstall some of them. Doing so might have unintended effects.

To remove the components:

1. Quit the following programs if they are running: iTunes, Apple Software Update
2. Windows 8: Click File Explorer > Settings > Control Panel.
   Windows Vista or Windows 7: From the Start menu, click Control Panel.
3. In Control Panel, click "Uninstall a program." The Programs and Features Control Panel will open.
   Alternately, if you don't see "Uninstall a program," click Programs and Features.
   
4. Select iTunes.
5. Click Uninstall.
6. When asked if you would like to remove iTunes, choose Yes.
7. After the uninstallation is complete, don't restart your computer if you're prompted.
8. If you see other iTunes entries in the list, remove them by repeating steps 4–6.
9. Using steps 4–6, also remove all instances of: Apple Software Update, Apple Mobile Device Support, Bonjour, Apple Application Support
10. Restart your computer.

Make sure that iTunes and its related components are completely uninstalled

In most cases, removing iTunes and its related components from the Control Panel will remove all supporting files belonging to those programs. In some rare cases, files might be left behind. After following the steps above, confirm that the following files and folders have been removed. If any are left, remove them.

• C:\Program Files\Common Files\Apple\Apple Application Support
• C:\Program Files\Common Files\Apple\CoreFP

If you receive a "Cannot delete iPodService.exe: It is being used by another person or program" message, follow additional steps.
