Can't use Microsoft Silverlight

   My PC has Windows 7, IE 11 and Norton 360, all with current updates.  I can successfully download Silverlight, but when I try to use it, the "bubble screen" hangs at 100%. I have another PC, similarly configured, but with Windows 8.1. Silverlight works fine on the 8.1 computer, but not the 7 computer.

 

   I've tried many of the simple fixes, such as redownloading Silverlight and making the web site in question trusted. I went to the Silverlight forum, but discussions there are way above my level of computer competence. Any ideas?  Thanks!

Hi, Patrick. I have Silverlight on my Windows 7 machines, and it installed fine.

 

Maybe the link here will have some answers for you. It's an old link, but may still apply for Windows 7
