I have a problem when publish application using copy and paste directly on user machine I face very bad error message appear when .NET Framework is not installed on user computer.
To run this application, you first must install one of the following versions of the .NET Framework: v4.0.30319 Contact your application publisher for instruction about obtaining the appropriate version of the .NET Framework.
My question is:
When user click on application icon I want to display custom message box tell user to use .NET Framework if not installed on user machine.
