In all the searches I've done I've found pretty much all the answers I need, except for one...
When I do the unattended installs, yes PDVD5 installs silently, but when I go to run it after the setup it asks for the CDkey, so how do I integrate the CD key into the install process?
Edit: Nevermind, I took a long close look at the thread I was looking at and discovered what I was doing wrong.... I was adding silent=1 in the custom.ini when I should've been...
