As I am sure you will have heard the MVC 1.0 has been released. I downloaded this on my Windows 7 and tried to install it but got an Error 1722, the MSI then rolled back.

Turns out the problem was simply that I had Visual Studio open at the time I installed, it needs to be closed. It seems the MSI does not check for this before it attempts the copy.
