I've set my environment variable UI_CUST_ADMIN_DIR and pointed to our folder on the server.

I've created my files in that server folder (unless otherwise stated, I set-up everything as we like, saved it, and then I copied the files from my local drive onto the server):
creo_schematics_admin_customization.ui (Created from scratch and currently empty)

And nothing works (on anyone else's machine - mine still has them saved on the local drive). Obviously, I need to put something in the admin customization file, but I cannot find any guides anywhere on what is needed to reference these other files.

Can anyone help me to get this to work? Thanks in advance!
