Hello Mudpie,
The CD shipped has most likely ancient software. Good thing it didn't install on that Windows version.
Let's try something else.
From the ZIP version available in
http://www.displaylink.com/downloads/file?id=1165
Decompress it, then got to the machine folder
DisplayLink USB Driver Package for Windows Preinstall (.INF) 8.5 M1\WinRS\x64
Right click on
dlidusb.inf and select install.
Then, plug in the device to your machine.
Kind regards,
Alban
