John T. Smith's input sounds sound, there may be one block in pursuing that suggestion.
I would agree with John T. Smith that Adobe is the one to sort out its Adobe Tech document for you if it will. It often restricts its assistance if the matter does not relate to purchased/registered/current version. And, Premiere Elements is not the current version.
Have you contacted Adobe about this matter and been refused help for the reason that I referred to?
And, out of curiosity, I would ask "Does the following apply to you?
Only Enterprise customers can perform the following procedures to silently install Adobe Premiere Elements 10 on Windows with an Adobe volume license (AVL).
What computer are you using and how many installation discs do you have?
Adobe is indeed your first choice, maybe your only choice, on this if it will help you with version 10.
