Help accidentally delete Itunes in my computer?

What should I do? The ITunes belongs to my daughter and now her Iphone 4, is no working.
How I can recovery ITunes in my computer after delete?

When you say you deleted iTunes, did you mean you uninstalled it? Go to the following location of your computer (replace you_user_name with your actual username) to see if the iPhone backup is still there.

C:\Users\your_user_name\AppData\Roaming… Computer\MobileSync\Backup

Normally, there should be some folders with very long names and pretty big in size. If they are still there, you can try reinstalling iTunes.
