If you pulled the jumper off a peripheral, then you'll have to consult that device's manuals for the proper settings. You could also just call NEC, the computer's manufacturer, and ask them what the jumper settings should be. Go to the folder in which your new program resides. Pinpoint the file that runs the application itself. This file virtually always ends in exe.
Some programs have several utilities or sub-applications, each of which can also end in exe.
If you run up against such a scenario, scrutinize the icon for each exe file. The one you want usually sports an icon that looks like the program's logo. If that is not a giveaway, you'll just have to launch each application until you hit upon the exe file you want. Once you have done that, close the program, return to Explorer, place your cursor on the file you have determined launches the program, and right-click on it with your mouse. A reference to the program stays in the Start Menu.
