I'm running Win7 x64 and IE8 with all updates and patches installed. I just tried to access a few of the virtual labs (Exchange 2010, Sharepoint 2010, Forefront) but all of them are stalling at "Checking ActiveX Control" after passing all the prereqs fine.
I've tried disabling/enabling and reinstalling all the add-ons, registering the mstscax.dll, running IE as Admin, and combinations of all of these, but still no go.
Any suggestions?
