I have a windows application which lets say Depends on X third-party application which i have its installer file.
i wanna do this:
Deploy my application in a way that it would check if the application is installed other wise use the included installation file to install it,
How can i gain this using Visual Studio Installer Project?
You can select prerequisites for the default installer, too:

That should do the trick.
