Web mail blocked patch doesnt work



People who use Windows Vista can't work correctly with Web Access for
Exchange Server. We use Exchange 2000. We called Microsoft to get the patch
that should fix the Problem. But the patch won't install. There is an error
that we don't have all prerequisities, but we have SP4 for Exchange
installed. We also used Windows update to install all Updates but it still
didn't work. Here is the logfile
