If you do not have .NET 4.0 installed, you will need to do so before continuing.

aspnet_regiis.exe allows you to register ASP.NET in IIS and update the script maps for all application pools or specific paths.

Run Command Prompt as Administrator.

32-bit machines:

%SystemRoot%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis -i

64-bit machines:

''%SystemRoot%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis -i ''

NOTE: If you receive the message “aspnet_regiis is not a recognized operable program or batch file” when you run this command you may be missing key files in your .NET 4.0 install. To fix this: visit the following website, http://www.microsoft.com/en-us/download/details.aspx?id=17851, and install 4.0 again.

Where path is the root directory of the website in IIS. 32-bit machines: code_formatdos|code_formatdos|code_formatdos|code format="dos"

%SystemRoot%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis -iru

%SystemRoot%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis -s path

<code> 64-bit machines: code_formatdos|code_formatdos|code_formatdos|code format="dos"

%SystemRoot%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis -iru

%SystemRoot%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis -s path
