So are you saying that the built in Win PE4 that is part of the core DS 7.5 solution is not supported? They do not give you any options for building older PE versions in the altiris console or the bootwizard that I can see, PE4 is installed as part of CMS 7.5 and I don't see any method for building and using older versions? If there is an article for how to do this could you please link me to it.
When I tell the system to build a PXE boot image 32bit WinPE 4 that actually works, just the automation folder does not, which I would assume is using the same WIM file, just one is being delivered via PXE and the other automation folder.
I did open a ticket with support last week, still waiting for them to troubleshoot my issue though.
