labview 3.1 serial number?



I have in a CD a very old version of labview 3.1 (fortunately, years ago I transferred all the diskettes I had - 3.5" and 5 1/4"- onto CDs and discarded all the diskettes), but I don´t find the serial number. I have tried all the combinations but no luck. What is the pattern of the serial number for labview 3.1?


xnnnnn? (like A12345)

xnnxnnnnn? (like A12B12345, used in labview 6)


both examples doesn´t work in labview 3.1

Hi asensio,


why don't you call your local NI representatives and ask them for all legal/licensing issues?

Hi, asensio,


it is diffucult to know since there are lots of years since LabVIEW 3.1 release. I think S/N have not changed. Why are you trying to license that LabVIEW version? The OS should be really old...


The best way to proceed in this case is phoning your local NI branch and asking them directly. If you are spanish, the telephone number is 91 640 47 64.
