missing DU.DLL and WinSetup.dll files

hello all,

I received purchased a copy of Windows 7 via a student discount through journeyed.com and received it today (despite it being days before the official release date). i popped the disc into my computer, did the Upgrade Adviser, but once I clicked on "Install Now" and error dialog said i was missing DU.DLL and WinSetup.dll files. upon further investigation, i found the two files hidden deep within the "sources" folder and all lowercased. I tried renaming them as to match the case in the error dialogs but it wouldn't let me. any advice?

much appreciated

Can you perform a "clean" install with this disk.

Upgrading leaves hundreds of files on your system that are of no use.
