I have IE 5.50.4134.0600 update Versions: SP2 installed under Win 2000 pro. I downloaded Microsoft's latest security patch q316059.exe. When I execute this program it simply states that IE 5.5 SP2 is required. I had the same experience with an earlier security patch. Clearly the update does not recognize the IE level reported to me under help/about. Does anyone understand what is going on here and what must be done to fix it?
