When the Orcas Beta 1 came out, I eagerly downloaded it from my MSDN Subscription on my home machine (no way am I letting it touch my main work machine just yet!). 

I couldn’t even get through the installer - it just complained about something not being right (I forget what). Brian Masden is encountering similar issues it seems - although he seems further along than me.

If an MVP can’t get it running on a clean Vista box - no wonder I’m having zero luck!

Keep fighting the good fight, Brian!
