Getting Error "The 'targetFramework' attribute currently references a version that is later than the installed version of the .NET Framework"

I've published an ASP.NET Web API on IIS7 server. When I'm testing it locally. I get a framework error below:

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: The 'targetFramework' attribute in the <compilation> element of the Web.config file is used only to target version 4.0 and later of the .NET Framework (for example, '<compilation targetFramework="4.0">'). The 'targetFramework' attribute currently references a version that is later than the installed version of the .NET Framework. Specify a valid target version of the .NET Framework, or install the required version of the .NET Framework.

Source Error:

Line 20: </appSettings>
Line 21: <system.web>
Line 22: <compilation targetFramework="4.5" />
Line 23: <httpRuntime targetFramework="4.5" />
Line 24: <authentication mode="None" />

I'm not quite sure what it is wrong as I have an ASP.NET website running on the server using framework 4.0.

Instead of installing .NET 4.5, you can change your application framework from 4.5 to 4.0 You can do this by right clicking on project -> Properties -> Target Framework.

Download .NET 4.5 from here after successfully installation run command prompt(as administrator) and locate to this address:

%windir%\Microsoft.NET\Framework\v4.0.30319

now run this command:

aspnet_regiis -iru

Specify a valid target version of the .NET Framework, or install the required version of the .NET Framework.

You need to install .NET 4.5 on the server where the website is running.
