How to promt the user to install the required .NET framework if it is not installed.

Hi,

I have .NET application which requires Framework 4.5. Currently I have written a config file which shows an error message to the user that the Framework is not installed (attached screenshot and config file)

Now i have the requirement, where the message box should also give a button to install the required framework from Microsoft site. Because most of the users dont know from where they have to download.

Can you help with some solution for this.

1. <configuration>
2.   <startup>
3.     <supportedRuntime version="<version>"/>
4.   </startup>
5. </configuration>

Thanks

Karthik
