Can't Open OpenGL subsystem!

I have a problem with a Nvidia Geforce 2 MX/MX 400 using Return to castle Wolfstein.
The installation program says :can't open OpenGL subsytem!!
Where can I find OpenGL driver for my Video schede?
I have just downloaded the last driver for my schede, 52.16_win2kxp_international_whql and nForce_2.45_WinXP2K_WHQL_international, but they don't work.
Thanks for all reply.

Why are you installing Nforce drivers? You want to royally screw up your system?

Do you have Windows XP?

Try these drivers:
