To follow up... from the command line:
troff -v
... executes fine
Then when I try
groff -v
... it executes, but I get the troff permissions error.

Thank you for all your help!
We tried the suggestion below, and the grops error has stopped, now we are only
getting a troff permissions error...
"Groff: couldn't exec troff: Permission denied"
Thinking this to be simple enough... I made sure each folder had sufficient
permissions, and I made the user owner of each folder and sub-folder... but
still no go.
Any idea what permissions are lacking?
My Perl script makes a call to the following folders:
C:\Ghostgum\gsview\..
C:\gs\gs9.04\bin\..
C:\GnuWin32\bin\..

Hi charlie,

Hard fiat currency!? Now you're talking. :-) Well, maybe not. See if this
works out for you.
I've took grops.exe from
http://sourceforge.net/projects/ezwinports/files/groff-1.21-w32-bin.zip/download
mentioned in
http://lists.gnu.org/archive/html/groff/2013-10/msg00001.html but you could try
starting with your existing one to save installing something new. Its SHA1
digest is 4e8639f4f7b67a9aff785053132d97b71615b784.
It has no symbols but I tracked down gen_tempname() and found
ba 80 01 00 00 mov $0x180, %edx # S_IRUSR | S_IWUSR
b8 02 05 00 00 mov $0x502, %eax # O_RDWR 2 | O_CREAT 100 | O_EXCL 400
The comments are mine. O_BINARY on Windows seems to be 0x8000 (thanks, Debian
Code Search) so we need that second instruction to be
b8 02 85 00 00 mov $0x8502, %eax # O_RDWR | O_CREAT | O_EXCL | O_BINARY
I checked that byte sequence only occurred once in the exe by printing the
zero-based offset of every occurrence.
$ perl -0777 -ne 'while (/\xb8\x02\x05\x00\x00/g) {print pos() - 5, "\n"}'
grops.exe
111706
$
Then I got perl to substitute it, backing up the original.
$ perl -i.bak -0777 -pe 's/(\xb8\x02)\x05(\x00\x00)/$1\x85$2/' grops.exe
$
And listed all bytes that differ in octal with their 1-based offset.
$ cmp -l grops.exe.bak grops.exe
111709 5 205
$
Giving a new SHA1 of
$ sha1sum grops.exe
b30cc09eb0f7cd24104a6ca207849ceb54233b40 grops.exe
Which you can find for a week or two at
$ curl -sS http://inputplus.co.uk/ralph/grops.exe | sha1sum
b30cc09eb0f7cd24104a6ca207849ceb54233b40 -
So, either try that grops.exe along with the rest of the above
groff-1.21-w32-bin.zip, or follow along at home with your existing one to see
if it modifies in the same way. Look out for the permissions on the downloaded
grops.exe or your own created one; it will possibly be a plain file and need
fixing.
Cheers, Ralph.
