Hey there!

It sounds like you are having trouble updating iTunes, even though you are connected to the internet. I would start with the troubleshooting in the following article to help resolve any software conflicts, or security software issues:

Resolve issues between iTunes and security software

If this does not resolve the issue, I would next remove the iTunes software (this will not compromise your iTunes library):

Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8

Or

Removing and Reinstalling iTunes and other software components for Windows XP

Then download iTunes with this link and install it:

Thank you for using Apple Support Communities.
