Uh oh, I was just doing some work in it this morning and EZP (v14) froze up. (note: this is only on my office computer, on which I run a copy for testing before I change things on the main registers; I have Windows 10 on this computer, and W7 on the active ones; I have a network connection between the active ones, but not between the one in the office and the active ones).
I copied the ezp folder from the active register to update my office copy, did a "check stock" report, and when I went to print it do pdf, ezp froze up. I tried opening it again a few times, and it kept freezing up on opening.
I've rebooted, un- and re-installed, uninstalled and deleted the folders in Public files and Program Files before reinstall, I've tried reinstalling earlier versions of v14 as well as the latest - all to no avail. It keeps freezing on the opening screen after reinstalling.
Of course, I'm in no position to say whether it's Windows 10-related or not. But I'd guess there's an easy fix - I'm just not sure what else to try.
