Open External Program - Unity 5

Question

I already know how to run an external program within unity using Code (CSharp): System.Diagnostics.Process.Start("C:/users/myname/desktop/fceux/fceux.exe"); However, what i want to do is keep fceux/fceux.exe within the games files itself, that way when I build it, everything comes with the game (in this case, my application).

From what I read online, i would need to keep fceux/fceux.exe in the same directory as the launcher, however with Unity 5 I can't seem to find where that's at in my project folder. Where do I need to put the folder?

Put the file in a folder called StreamingAssets. The file will then be included in the data files that come along with the launcher. The path of the executable at runtime can be determined like so:

 string filePath = System.IO.Path.Combine(Application.streamingAssetsPath, "fceux.exe");

I added it to the games files, and my files go: game -> Assets, Library, ProjectSettings, Strea$$anonymous$$gAssets, Temp, etc. and then from there Strea$$anonymous$$gAssets -> fceux -> fceux.exe, other misc. files related to fceux

yet i still get the error that it can't find it? Here's the code i'm using:

 public void PlayGame() {
         string filePath = System.IO.Path.Combine(Application.strea$$anonymous$$gAssetsPath, "/fceux/fceux.exe");
         System.Diagnostics.Process.Start(filePath);
     }

Oh, the documentation doesn't make this totally clear, but Strea$$anonymous$$gAssets should be inside the Assets folder. You'll know it's working properly if any assets placed inside of it are not imported by Unity (e.g. an image file is just treated like a file rather than a texture).

see, i thought about that and put it in the Assets as well, and it still didn't work.

Can you confirm that dragging an image file into the Strea$$anonymous$$gAssets folder is not imported? When you say it "still didn't work", is there an error? Does nothing happen?
