Photoshop/Premiere 10 upgrade from 5 installation trouble

[Guest]

Having trouble installing Photoshop Elements/Premiere 10 upgrade from 5 on my pc from the installation discs. AutoPlay doesn't start; when AutoPlay.exe is selected, message reads: Invalid Unicode file:  .\AutoPlay\LangData\en_US\lang.dat.  Please help!

try to click the Setup.exe instead of clicking the auto play..

Elaborating on Johan's reply: Open the CD in Windows Explorer, and double-click Setup.exe instead of relying on the CD to Autoplay.
