Select ASP.Net framework 4.5 as target framework?

Question

I am trying to set my projects framework target to ASP.Net 4.5 but am no able. I downloaded the ASP.Net 4.5 framework from the microsoft website but when i try install it i get the message:

Same or higher version of .NET Framework 4.5 has already been installed on this computer.

But if i look at my projects property page, Framework 4.0 is the highest i can select?

Please can someone tell me what i should do?

Thanks in advance.

Visual Studio 2010不支持它。您需要Visual Studio 2012。
