We're sorry, but the Prism version 8 Console has not been fully regression tested for use on Vista. That’s why you only see the Package Builder component and not the Console as a choice when you’re installing.  We plan to support installing the Console on Vista in our next maintenance release, currently scheduled for Q1 of 2008.  For the time being, the Console needs to be installed on XP, Windows 2003 or Windows 2000. We also plan to add 64-bit support in that release.
