Now let's add the Microsoft.CSharp assembly to the project reference so that we can use dynamic programming.

Now let's have a Button which will display the OS version when it is clicked.

On the click event let's write down the following code.

As you see in the above code display, we are first checking whether the application is running in OutOfBrowser mode and the application should have Elevated previlage.

Then we are checking whether AutomationFactory is available. If it is available then create an object os the WScript.shell.

And finally out of that we would get the registry key value.

Now run the application and install the application on the client machine.
