Hi all,

I have a few issues that crept up all of a sudden with my PC running

This started off randomly when I opened the program after work the other day
after having spent and evening prior working on a project. The app loads the
editor, the console and the code from the selected project but no
render/preview window. Hitting F5 or the option in the menu appears to run
fine in the console but thats as far as it gets. Hitting F6 however stats
the render and gets to approx 475/1000 before the app closes and drops an
error in my event viewer which doesn't show much of anything:

Faulting application name: openscad.exe, version:, time stamp:

I have tried the whole uninstall>reboot>install routine many times and even
using the binary, not the installer.  Falling back on my Sysadmin methods I
decided to try and run the app from the CLI as my user and as admin and this
is where I am finally seeing some details that I need some insight on.
Running the app from the CLI I get this after opening a new or existing
GLEW Error: Missing GL version

I know that GL is up to date and my drivers have been both reinstalled and
then updated when the results were the same. Render shows this in the CLI
(the first line is on open of the .scad file, the rest on crash):

GLEW Error: Missing GL version
CGAL error: assertion violation!
Expression : object_list_
File       : ../src/OGL_helper.h
Line       : 571
Refer to the bug-reporting instructions at

I tried to open Help>Library Info and get this:

GLEW Error: Missing GL version
terminate called after throwing an instance of 'std::logic_error'
  what():  basic_string::_M_construct null not valid

Finally I tried to run "openscad.exe --info" and got this and the app failed
to load at all:

Sorry for the long post, my sysadmin work taught me that there is no such
thing as too much information.
