Check that ActiveX Filtering is disabled.
I disabled Active X Filtering and was still unable to open. But then I tried it in Firefox instead of IE and I was able to view the item.
I still get an error message when I try to view an item that requires Flash.
What is the error message?
It says that I need to install Flash Player 10. But when I click on the icon, I get the page that says it's already installed with Windows 8 and that I should enable Shockwave Flash and disable Active X filtering. I did both of those things in Internet Explorer with no success. Was only able to view my slideshow when I opened the website in Firefox.
