The AudioDrive.exe file is a self-extracting ZIP file. After downloading it onto your system, create a directory on your HDD called AudioDrive, move/copy the file to the new directory, and launch the new file to unzip the drivers into a Win95 subdirectory. From Settings->Control Panel, choose the System icon. Click on the Device Manager tab and double click on the "Sound, video, and game controller" icon. On the ESS ES1868 Plug and Play AudioDrive pop-up window, left click on the Driver tab.
Left click on the [Update Driver] button and click through [Next] until the [Other Locations...] button appears. Browse to the new AudioDrive\Win95 directory and click the [OK] button to load the correct driver files.
