|You don't "run" a floppy disk, to use, copy, run, etc, the data that is ON the floppy disk.|
Therefore there must one or more files ON the floppy that you can "run" If, for example, there is some sort of text file or document, you can open that file with a program like word, wordpad, notepad, office, whatever. You would do this like you do ANY file---Use Widows Exlpoder to "explore" the floppy drive, and when you find the file you want, click on it, or right click and see if there is an optional "open with"
Now, can you be more specific? What is supposed to be on this floppy? What have you done with it?
(You can't just jam/stick/shove/place/insert a floppy into the drive, and expect it to "run" all by itself.)
Last, in my opinion, "autorun" on a CD was the single most infuriating "feature" that was every applied to a computer by any software writer.
