Q: will not let me enter answers for security questions when checking on devices

Hi auxarc,

Thanks for using the Apple Support Communities!

Fro your post, I understand that you have two separate situations happening that you need some assistance with. 

We’ll begin with iTunes. You should be receiving a prompt to Run or Save the iTunes download when you see the page you mention as described in the following article. If you do not see the option to Run or Save the application, please follow the steps in the following article. 

If you can't download iTunes for Windows using Internet Explorer - Apple Support

I understand that you are having issues entering your Apple ID security questions as well. It may be necessary to reset these security questions. The following article explains this process.
