I have installed the Asus Xonar D2X soundcard and it works great in both XP & Vista 64bit. It came bundled with a bunch of software (Oem Versions). Anyways, I tried to install the software and on opening the software it asks for Install Key... Theres no piece of paper with these keys in, just the drivers discs and some other software titles and the soundcard wires. I have tried in both Win XP pro 32bit & Vista Ultimate64bit. Am I being thick here, or does anyone else know how to get the free OEM software working. I really want PowerDVD V7.. and it is supposed to be free with this card.
