Thanks for your update.
Please select Uninstall option. This will uninstall iTunes only. Your info and songs should be fine. When done with uninstall, reboot your computer. Then run the installation again and this will install iTunes again.
If that does not work, we will have to manually uninstall iTunes and its components as follows:
Use the Control Panel to uninstall iTunes and related software components in the following order and then restart your computer:
- Apple Software Update
- Apple Mobile Device Support
- Apple Application Support (iTunes 9 or later)
Important: Uninstalling these components in a different order, or only uninstalling some of these components may have unintended affects.
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 those though, files may be left behind. After following the previous steps, you should confirm that the following files and folders have been removed. If any are left behind, remove them now:
- C:\Program Files\Bonjour
- C:\Program Files\Common Files\Apple\
- C:\Program Files\iTunes\
- C:\Program Files\iPod\ Note: Follow the additional steps at the end of this article if you receive the alert "Cannot delete iPodService.exe: It is being used by another person or program" when trying to delete this folder.
- C:\Program Files\QuickTime\
If you have a 64-bit version of Windows, you will need to confirm that the following folders have been removed as well:
- C:\Program Files (x86)\Bonjour
- C:\Program Files (x86)\Common Files\Apple\
- C:\Program Files (x86)\iTunes\
- C:\Program Files (x86)\iPod\ Note: Follow the additional steps at the end of this article if you receive the alert "Cannot delete iPodService.exe: It is being used by another person or program" when trying to delete this folder.
- C:\Program Files (x86)\QuickTime\
After this reboot your phone and install iTunes again. Test iTunes to see if it will work or not.
