Thanks for trying, but it didn't work.  Still cannot open Quickbooks and getting same Warning.  Also... how do you expect us to update our software if we cannot open it?  The IE mode was set to "Allow" when I got there following your suggested steps.  Looking through the web, I am not the only QuickBooks user having this same problem. (complete understatement) I have not been able to use my business QuickBooks software now for approx. 3 weeks and I don't think I need to tell you how much that sucks.  Please get a fix for this problem soon.
