Driver tested good for Win95,98,98se, and Me. Driver for NT4.0 is available at IntreSource's FTP site ftp://ftp.intresrc.com/drivers/terasound/
It says that the driver is native to Win2000 and WinXP.
ts64-128.zip unzips into 3 other zip files, all downloaded from IntreSources's ftp.
Just unzip them all to the same folder, and reinstall the driver from Device Manager.
