ASP.NET 4.5 has not been registered on the Web server

asp.net-mvc-4iis-7.5localdbsql-server-express

In my Win 7 development machine, and in order to use SQL Express instance instead of the localDB installed by default. I unchecked "Use IIS Express" in my MVC 4 project properties page (Web tab), then I got the following error:

ASP.NET 4.5 has not been registered on the Web server. You need to manually configure your Web server for ASP.NET 4.5 in order for your site to run correctly.

I verified that ASP.NET is activated within the IIS features.

Please what could be done to resolve this?

Maybe you have to execute the following in the Visual Studio Tools command prompt:

aspnet_regiis -i
