Now, I understand.

Could have done that some time ago. Some of these things go
unexplained at the WinTopo web site system requirements. Did not
understand why to choose certain operating system. Though all the same.

I prefer working in Win. 98 as it is well accepted by machine tool
manufacturers in my area, even today. Win. 98 does have a 32 bit
operating system available, and am operating one computer on that now.
It does cause file transfer problems when going back to a 16 bit
system to which the machine tool interfaces operate on.

Will be contacting you for correct version soon. Need to update
computer here then, and make ready.
