Visual studio pro 2012

Hej
Jeg har problemer med visual studio pro 2012 når jeg bruger webmatrix3 til at installere umbraco jeg får fejl der siger:

-- we couldn't install Umbraco CMS
    downloaded

- ASP.NET MVC3 tools update installer
    This product did not install succesfully

- ASP.NET MVC3(visual studio 2010)
    This product cannot be installed because a product that it depends on did not install successfully.

Nogen der kender til dette?
