The last driver released for this card was for XP. I have checked compatibility center and do not see your card listed. You can try uninstalling the driver and reinstalling it to run in compatibility in XP mode to see if it will work. To run in compatibility; right click the installer> select the compatibility tab> check the "run this program in compatibility mode for:" box> then from the drop down, select Windows XP. It may not work. But you can try. The current drivers for your Sound blaster PCI 64bit are here
. Windows Compatibility center is here
. In the Compatibility center you can chose to "Scan your pc for compatibility." Best of luck.
