I use 2017 Appliance with update 2.
As I see in the documentation, I can use the wimprocessor tool to make winpe boot cd.
I download the 3PIUtils folder to my workstation. The command what I am use, and the result:

d:\winpe_cucc\wimprocess.exe makeiso x86 d:\winpe_cucc\3PIUti

ISO file is being created. This might take a while, please wait..
An error occurred while mounting the image
The system cannot find the file specified.

Failed to create WinPE ISO

In the log I can see the next:
Destination directory exists: D:\winpe_cuccok\WinPE_ISO
Unable to Mount wim Image

If I run command without "zenworks folder" argument, the iso make succesfully.

What is the problem?
