We recently moved our Fluorolog-3 equipment and after reassembling it, and when starting the Fluoresscence software we got the error described by you in your manual "Error message: Origin 8.1 Unable to start Origin. Please insert hardware key before starting Origin", so we cannot start the computer. According to our local distributor all hardware is working OK, but te local distributor could not fix the error. According to the manual our equipment does not use a floppy disk for start running but the floppy disk drive is dissabled.
