6.11.4 is very old, likely because you installed it from the CD and forgot to run the update. Although it should still work without updating, I tried Googling for the specifications of the ze4111 to see what video card it has. Knowing what video card you have will greatly help. Some users here do use notebooks without problems (even old ones) so that isn't the case. If you don't know what video card you have, there are two ways:

Both cases:
1. Access your operating system's control panel (I've never seen nor used Windows NT so I don't know how different it is).

First method (easiest and safest):
2. Double-click "display" and go to the settings tab. You should see color depth and resolution settings here.
3. Above the resolution and color depth settings, and below the monitors, you'll see the graphics adapter. See my screenshot here for what you may be seeing (in Windows XP anyway). I have GeForce 7600 GT, yours will certainly be different.
4. Click the cancel button - you haven't made any changes and they don't need to be saved (unless you made one yourself).

Second method (a bit trickier, but less safe, use only if first method doesn't work):
2. Double-click "system", go to the hardware tab, and click on "device manager".
3. Click on the small plus sign to expand the "display adapters" list and you should see it. I snagged another screenshot to show you what I'm referring to for this method.
4. *important* Do not make any modifications here, rather, just close any windows and click the "cancel" button instead of the "OK" button to ensure no changes are made.

Edit: forgot to change the URL to the second screenshot....
