Vmware workstation player v15 not pulling through Autounattend file?

Hey Guys

In need of help please.

I am using engl imaging software to create a new base Windows image...I placed the files needed onto a usb stick ($OEM$ and AutoUnattend.xml)

I then load the windows 10 Enterprise iso onto the new VM and enable the Usb stick, through the removable devices menu.

Using Workstation player v12 the process works as it should and I end up with a ztoolkit folder on the root of the c drive in the new vm.

However on V15 it does not seem to process the AutoUnattend  file/ once windows is loaded, there is no "ztoolkit" folder on the root of c:\

The config files for the v12 and v15 are attached.

Would appreciate some assistance please.

Thanks.
