Well, it's exactly what texdoc is supposed to do...

Known. start has a very wierd syntax.

So stupid of me. "texdoc -n4 minitoc" is the correct syntax, as you found out

>> C:\Documents and Settings\Administrator>texdoc -n32767 minitoc
>> texdoc debug1: start ""
>> "D:\TeX\Live\2008\texmf-dist\doc\latex\minitoc\minitoc.pdf"

This I cannot understand. The two relevant line of the code are:

        err_print(view_command, 'debug1')
        view_result = os.execute(view_command)

As you can see, texdoc doesn't lie to you: it really tries to execute the
command it says it does. Can you please try the following minimal texlua code?

os.execute('start "" ' ..

(put it in a file an run texlua 'file')

When the first argument to start is quoted, start assumes it's the (optional)
title of the new window. So the purpose of the initial "" is to prevent start
from thinking the quoted filename is the title.

I just come to think of it, maybe AR doesn't like this empty title setting.
What I really can't understand is why the same command works when directly
typed in the command line.

texdoc, live, latex2e, impatient, hyperref, beamer, pgf, (in theory any recent
LateX package you can think of).

>> C:\Documents and Settings\Administrator>texdocc -v minitoc
>> I now display a document by the command
>> cmd /c start d:/TeX/Live/2008/texmf-dist/doc/latex/minitoc/minitoc.pdf
Ok, so maybe I should use a similar command line from texdoc too.

Thanks a lot.

Actually, I have very few knowledge of windows, and for some reason AR doesn't
want to install on the only copy of it I have, so I can't even test things
