I'm using PiCTeX under Windows 95 or NT. Even after I've installed it correctly (see previous entry) the typesetter can't find the PREPICTEX or POSTPICTEX files.
The old PiCTeX file distribution has names truncated at 8 characters. Thus the files on disk are named PREPICTE.TEX and POSTPICT.TEX. You should rename these files to PREPICTEX.TEX and POSTPICTEX.TEX respectively. You may use File Manager, Explorer, or the command prompt to perform this renaming.
Example using the command prompt:
cd\pctex32\texinput ren prepicte.tex prepictex.tex ren postpict.tex postpictex.tex
