The Windows NT driver is an information file (.inf ), not a setup application file (.exe). Therefore you should choose the 'Drivers' icon in the 'Control Panel' window of Windows NT, and then 'Add' this information file from the following location on this CD-ROM
D:\APP\PRODUCT\7\9685VGA\WINNT4\
(Note : 'D' represents your CD-ROM drive assigned letter - please change if necessary)
