Mifare Change Serial Number
Mifare Change Serial Number Iphone X
You're very welcome.I just did a search of the HP business support site's entire driver section and that utility no longer shows up.I don't think that using that utility (if it worked on the Z400 at all) would resolve the online utility problem.But I guess you have nothing to lose by giving it a shot.I had bookmarked the link to the driver so that gave me the name of the utility.Though it is gone from the HP website, I googled the name and found it on a 3rd party website.I have zipped up and attached it below. I checked it for viruses and whatnot. Looks fine to me.You will need to follow the instructions I posted a few years ago. You must use a USB FDD.
