Do you have the latest version of the utility already?
If so, I'd just toss it, download the 70 odd mb file from hp's download section, and use that.
Make sure you toss the entire previous utility file.
I'm a beginner so don't rely on what I'd do.
I'd also make sure I performed maintenance to the Z while I'm at it.
Yep toss the old download the new, hard reboot the printer using the new utility.
Import or create the new profiles using it.
I would shy away from firmware updates if your Z is chugging away.
Over and over I've been reading about buggy woes as the outcome for some % of users.
So again, I'm a beginner and wouldn't listen to anything I said if I were you,,,
also I'd unplug the computer from the printer before doing this nonsense
