I am followed the video and It worked fine but then it started doing this after the first update.
Error starting application:
System,ComponentModel.Win32Exception (2); The system cannot find the file specified.

System, Diagnostics;Process,StartWithCreateProcess(processStartinginfo startinfo)

  Can someone please help?

You probably set up your zip structure wrong, make sure the .exe is in the first folder.
