You can just execute your main exe by checking the "Execute file after update" checkbox. See "Executing files in your update". Make sure you uncheck "Wait for execution to finish before continuing."
Relaunch app after update
erikestCurrently I run wyupdate with -quickcheck -justcheck to see if there is an update before launching the splash screen and main form of my app. If there is an update, I close my app and run wyupdate, which updates the app fine. What's the best method to then have my newly updated app launch again after wyupdate has done its business? Is there a command line switch for performing a post update restart?
