Fun times with an Art Professor
Once had a fun one in Academic Computing. Most of the campus was PC, but of course the art dept will have their Macs... (this is a story so old it's pre-windows!)
So of course, art dept chair wants to know how to protect his work on the 40 MB (not a typo, this is an old story) Mac SE. We orderd him a copy of Redux (popular backup software of the day) shipping to his office, and told him "Give us a call when it's in and we'll send someone over to your building to get you set up."
A few days pass and we get a call - not, as one might expect, asking to have someone over to set up the new software. No - this professor called to complain that the software wasn't working!
A little investigation revealed the reason - somehow he'd gotten to the point in the manual where it described how to run a backup (place a blank floppy in the drive, when it fills up, take it out, label it, and place the next floppy) while entirely managing to miss out on the part where you install and run the software!!!
So he had been sitting there for an hour, swapping in blank floppies, waiting a few minutes (for what I'm still not sure), taking them out, labeling them, and going on to the next one... at some point he'd started suspecting that the software (still sealed into the envelope, still in the box) wasn't working and placed the call to support.
We gently explained that in order for the software to work, you have to actually install it, and then, yes, even run it.
