detect if the normal or DirectToRift.exe is launched?

I've looked in a couple of previous threads but it seems like there isn't a quick call to figure out which .exe your user launched with. Though, you can write your own which works really well. Here's a snippet of my code that I got inspired to write after another thread on this matter:

IEnumerator DetectOculus()
	{
		yield return new WaitForEndOfFrame();	// Let Oculus stuff initialize (I needed it for my project)

		long exeSize = 0;
		{
			FileInfo exeFile = new System.IO.FileInfo(Environment.GetCommandLineArgs()[0]);   // Path name of the .exe used to launch
			exeSize = exeFile.Length;   // exeFile.Length return the file size in bytes. Store it for comparison
		}

		// Use file to determine which exe was launched. This should be stable even if a user changes the name of the .exe or uses a shortcut! =D
		// Direct Rift sizes: 184320 is 64bit size, 32 is 164864 (3rd check is for extended mode(NOT FULLY TESTED)) 
                // (You may want to use Debug.Log(exeSize); to double check the file size is the same on your match)

		if ((exeSize == 184320 || exeSize == 164864) || (OVRManager.display.isPresent && !OVRManager.display.isDirectMode))
		{
			// DirectToRift.exe
		}
		else
		{
			// Standard.exe
		}

This might not work if you update the drivers, but I don't think the drivers will change the .exe sizes of older versions so I guess it should keep working.
