Hello Burlen,
Problem solved. The NVIDIA driver 307.83 allows using the Version 2 LIC
plugin pf PV 410 with my old GeForce 8700M GT card, and all my other old
graphic software (including games!) seems to accept this new driver.
Thank you again.
Richard.

Hi Richard,
Your video card is fairly old and it doesn't support the extensions
used by the new version.
The 2.0 Surface LIC in PV 4.1 is a true parallel implementation and
has additional requirements compared with the original serial code.
However, there are no exotic requirements, all have been adopted into
the OpenGL standard many years ago. So most recent hardware/drivers
will provide the required extensions.
NVIDIA's spec
sheet(http://developer.download.nvidia.com/opengl/specs/g80specs.pdf)
doesn't show support for GL_ARB_depth_buffer_float. Based on the info
you provided that's my best guess as to what's wrong. However, I found
a mention( http://en.wikipedia.org/wiki/GeForce_8_Series) that the new
drivers for the 8 series support OpenGL 3.3, which includes floating
point depth buffer. Updating your driver may resolve the issue.
