I run the download script (a couple times now).
I say yes to overwrite previous versions
of nmake.err and nmake.exe, but nothing
shows up in c:\
when I type in "nmake" or "nmake15",
it returns "not recognized as internal or
external command, operable program or
batch file."
You probably already solved it by now, but here goes my 2 cents anyway.
Make sure you copy both files to a directory in your windows path. It will surely work.
