It turns out that my previous download troubles with IE9 were as a result of using the Google Chrome browser. When I view the site ie.microsoft.com/testdrive and try to download IE9 in Chrome I get an error message saying that my operating system is not supported. Viewing the site in any other browser (IE8 shown below, but Safari and Firefox work as well) then you get the proper download screen. Maybe this is an ActiveX thing that Chrome is blocking? Maybe it’s one of my Chrome extensions (I don’t use Adblock)? Anyone else have these problems?
