The file

	ftp://swi.psy.uva.nl/pub/SWI-Prolog/w32pl210.zip

contains  SWI-Prolog  2.1.0  for  Windows-NT.   The  system  should  run
out-of-the-box, but there is a little   filename  problem for Windows-NT
and Windows-95. 

All filesnames in the zip-files are the  short (FAT 8+3) filenames of NT
and some files in the library subdirectory   are truncated. Use the info
from library/dir.map to restore these files to their original names ...
