I downloaded and installed the iges2step software but it crashes on startup with the message "Fatal Error in units initialisation". I noticed its copyright is from 2003. Maybe there is problem with newer versions of the Microsoft Visual C++ Runtime like the 2005 one installed on my Windows XP Pro laptop.

Hi Al, I took a quick look and saw the same problem. The fix is to reboot your machine, it should then work after you have rebooted.

It needs a couple of environment variables set to work properly, on install the changes to the environment variables don't quite spread out to the entire system, but they will after a reboot.

It's interesting - appears to be based off of the Open CASCADE kernel. It's actually parts of Open CASCADE that need the environment variables set.

That worked. Thanks Michael.
