I'm just in the middle of setting this up on our CC4 Network.
So far ive got the exam centre service installed ok
packaged and rolled out administrator dashboard for CC4 (to one machine ha - makes rebuild easier)
packaged and rolled out invigilator dashboard for CC4 (to 5 machines ha)
packaged and rolled out test player for CC4 - I had to create a separate MSI for each room to I could default the invigilator name per room without manually doing it.
Got testing to do tomorrow. I must admit Pearson have the worst support ever. "we don't support silent installs, its beyond our scope" I've managed to package every bit of software (70+ packages) to silently deploy so if this doesn't work I wont be happy.

EDIT
Decided to test it out since i'm remote'd in doing some other work. Logging in the PC with the admin dashboard and assigned some tests ok, logged onto invigilator dashboard and unlocked them etc, created a new user student user, logged onto the PC with the test software installed and it picked the invigilator and everything up without issue.
Never had to copy anything to any profiles, maybe because a created my own msi for each room with the computer name already in?
