VS2K10 comes with MVC. If you installed one of the betas, it is not compatible. You should use the distributed version.
Did you install MVC 2 Beta? It's completely incompatible with VS 2010. You cannot install it on a machine where you want to also use MVC in 2010. You need to use MVC 2 Preview 2 (or earlier) for your VS 2008 projects.
You can also wait for the next VS 2010 beta, which will include an updated MVC 2.
