To get it to install on my Vista install, I first unblocked the EXE and then ran the MSI from a "Run as Admin" command prompt.

Initially I tried just double clicking on the MSI and clicking through all the normal security dialogs, but that didn't seem to work. Maybe I wasn't patient enough or had a running instance of IE in the background, etc, etc...

Still the second install try ("Run as Admin" comment prompt install) worked right off, so... draw your own conclusions. Your mileage may vary, yada...

On the IEBlog there's some more in-depth information and pictures... ;)
