Register .NET Framework 4.5 in IIS 7.5

Question

Pieces of the puzzle:

• Windows 7
• .NET Framework 4.5 (installed)
• IIS 7(Version 7.5.7600.16385)
• Visual Studio (Ultimate 2013)
• MVC4 (multiple projects in the solution)

The solution I'm running in Visual Studio works and runs as expected with IISExpress.

To set up my site to use IIS, I tried the following steps:

1. Right-click the projects in the solution that are currently being hosted by IISExpress.
2. Click Properties.
3. Toggle the Servers drop-down from IISExpress to Local IIS
4. Try to build/run the application

At this point, I get an HTTP 500.21 error.

I have also tried to run aspnet_regiis.exe -i using Visual Studio's command prompt (as an Administrator), but each time I run the command, I receive the following error:

Command 'aspnet_regiis.exe' is not valid.

I also confirmed that I do have the right aspnet_regiis.exe installed (by checking here) (.NET Framework version 4 (64-bit systems)).

What do I need to do to register .NET Framework 4.5 in IIS 7.5?

You can find the aspnet_regiis in the following directory:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319 

Go to the directory and run the command form there. I guess the path is missing in your PATH variable.
