How can I install .ipa file to my iPhone simulator?

I need to install .ipa file to my iPhone simulator.

I tried to change the extension .ipa to .zip and extracted it.

And I got the Payload folder and moved the application inside to my iPhone simulators applications folder found at: /Library/Application\ Support/iPhone Simulator/6.1/Applications/.

Application appears on iPhone Simulator, But the application did't running. How to solve the problem then how to run the app.

You can't.

IPAs downloaded from the App Store are built for the ARM processor in actual iOS devices. The iPhone Simulator is not an emulator and can't run ARM code.
