The file you got is the "source". That file should have a user interface, and a block diagram (unless this was removed). In order to run it, you must have the proper LV version to open it, and run it. Then, if you do have the labview application builder, you will be able to create an executable. You can take this to another computer and run it there, but with the need of the labview run-time engine in the particular machine.
Hope this helps.
