Newbie Query

Hi

I have just a quick query in the root of my USB i have the list of Portable Applications that i loaded from the application suite.

But when i have updated the different applications the .exe files dont work. I did try to create a shortcut which works on my main pc but when i go onto another machine the usb gets another drive letter so the shortcut does not work. How can i create a .exe file in the root that works because ifi i copy the exe file over from the new update it does not work??
