Hi Robert, I have updated the driver on one of machines. The 3D texture message is gone, but I got other message.
Warning: Could not find plugin to read objects from file "shaders/volume.vert". Warning: Could not find plugin to read objects from file "shaders/volume.frag". Locator::computeLocalBounds Scaling image from (350,350) to (128,128) Error Image::scaleImage() do not succeed : scaling of volumes not implemented. Scaling image from (350,350) to (128,128) Error Image::scaleImage() do not succeed : scaling of volumes not implemented. Any idea what is it? Thank you for your help again.

It would be possible to implement a crude 3D volume rendering based on 2D textures but it would be very limited in what it could do. 3D texturing has been a standard feature for graphics cards for quite a few years now so if one is doing volume rendering it's normally a reasonable requirement to have the hardware that is capable of handling the task. It also begs the question about just what hardware is in those WindowsXP machines, I asked this earlier but you haven't yet mentioned. Could it be some old intel hardware?
