Hi James, I'm not sure why it would be complaining. I'm running it on .NET 4.5. They can't run side by side but 4.5 should be able to run 4.0 apps.

Hi Kary -- thanks for this tool and the posts about it! It's a great resource. Is Microsoft / are you interested in potentially making this project open-source? I would love to understand the workings of this and see if I couldn't contribute something as well. If you're interested, shoot me an e-mail at SeanKilleen@gmail.com or on twitter at @sjkilleen.
