By default, an app runs on the version of .NET Framework that it was built for. If that version isn't present and the app configuration file doesn't define supported versions, a .NET Framework initialization error may occur. In this case, the attempt to run the app will fail.
To define the specific versions on which your app runs, add one or more <supportedRuntime> elements to your app's configuration file. Each <supportedRuntime> element lists a supported version of the runtime, with the first specifying the most preferred version and the last specifying the least preferred version.
对于你的程序：
<configuration>
<startup>
<supportedRuntime version="v4.0" />
<supportedRuntime version="v2.0.50727" />
</startup>
</configuration>
