How to connect iTunes account to Disney Movies Anywhere

This article: https://support.apple.com/en-us/HT202915 tells me how to connect my iTunes account via Disney Movie Anywhere settings. Okay, I do that and click on continue inside the settings to connect the accounts, and then it takes me to a page to downloaded itunes..... Problem is, I already have iTunes installed. I dont need to download it again. So the process of connecting the two accounts stops. Anyone know how to connect your Disney Movie Anywhere settings to iTunes when you already have iTunes installed?
