This used to happen when people had beta version of Internet Explorer installed because the McAfee UI is actually an Internet Explorer page and is independent of whether or not your default browser is I.E.. If that's not the case then try the following and if that fails contact Technical Support, free by phone or online chat, via the link under Useful Links at the top of this page..

It did not work for me, the first step I did. I did download the file it did ran then nothing came up...
Is this the McAfee software interface we are talking about or web pages? What browser is your default?
I had IE set to stop banner ads in another application, like this I got a blank panel for McAfee.
Do you have Content Advisor enabled in IE?
The desktop interface refers to your IE settings, so if this your problem....
Go to Tools, Internet Options
Select the Content tab
Either Disable Content Advisor
Go to Settings then the General tab
Check the top box "Users can see websites that have no rating"
Hope this helps.
