If you don't want to run the app as admin, you can also clear the security block on the application and that should let it run fine without resorting to Run As Admin. It happens because the executable file showed up from a foreign source and did not go through a proper installation.
Checking unblock should stop Windows from preventing the app from running.
Have you considered offering the apps in an installer? I could set you up with a simple one using Inno Setup (free).
