Celestia Forums

I have just downloaded Celestia 1.2.5

Installed OK

When I run it it comes up with message box:

The instruction at "0x00000000" referenced memory at "0x000000". the memory could not be "read"

I am running Windows 2000 Pro and have a NVidia Riva TNT grapics card.

Brett,

You need to upgrade to the most recent Nvidia device drivers at

The symptoms you report mean that you are using Microsoft's OpenGL v1.1 software drivers, which actually do not use your card's 3D graphics hardware.
