tried them but doesn't work either. Strangely enough driver does install, but when autoalign pops up, and activated, the computers hangs (really hangs, nothin left but hard reset!). Creative seems not to publish any drivers for Dxr2 cards for XP, so thats a mess!
Have you also tried to install the drivers manually?
In the device manager, you can right-click the unknown multimedia-device (the dxr-card), choose update driver, and then"display a list of known drivers for this device...", then choose "have disk" and point to where u have unzipped the drivers. The driver should pop-up in the list and choose to install it.
