MIL-W1897L cannot install device

I am having trouble installing the device on a Windows 98 laptop. (i know it's very old but i need this to work)

-After inserting the card into the PCMCIA slot, nothing happens.
-I go to the network connections and add a new adapter.
-Clicked on "Have disk..." and loaded the driver from the manufacturer.
-Driver installation went smoothly so I restarted the machine.
-After the reboot, no wireless adapter is detected.
-When I checked the Device Manager, I see a yellow mark on the device with a question mark. Upon click properties, it says,

"The NDIS.VXD, NTKERN.VXD device loader(s) for the device cound not load
the device driver. (Code 2.)

To fix this, click Update Driver to update the device driver."

-I followed other suggestions like copying the two VXD files into the system folder but to no avail.

Please help. Thanks.
