Installation for Windows NT 4.0 Copy the NT release kit files to a directory on your system, and start SETUP.EXE with a double click or by highlighting the file and pressing the ENTER key. You should see a welcome screen. Click on the NEXT button; you should see the modem in the display window. Click on the NEXT button to install the driver. If the installer tells you the modem driver is already running, you may un-install it using the Add/Remove Programs Control Panel applet. Select the modem, press the Add/Remove button and you will see the Modem Un-Installer Wizard. Press the Next button at the first screen and the Finish button at the second. You can now re-start the SETUP program. While the SETUP program installs the driver, you should see a few copy operations and hear a small flurry of disk activity, followed by the next screen, which says, "the following drivers were installed successfully." The driver is now installed and running.
