What you are looking for is the App.config of your application. It should contain the following xml: 

<?xml version="1.0" encoding="utf-8" ?> 
<configuration> 
  <startup useLegacyV2RuntimeActivationPolicy="true"> 
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/> 
  </startup> 
</configuration>

This information appears in the links you provided.

  • Where i can find App.config file. can you give me the path – BlackRoot Aug 06 '12 at 23:17
  • It should be in your Windows Application Project.. if it somehow doesn't exist there you can always add it yourself. Just create a file by that name, place it in your project's root folder and paste the XML above. – Jony Adamit Aug 07 '12 at 11:33
