[Groff] Installing/Running groff-1.21 on W7 x64

[John W. Smay]

I am loading up a new Windows 7 x64 (64 bit) computer, To particular with 
groff.  To a prior quiery about groff-1.20.1, Werner suggested I try
Eli Zaretskii's groff-1.21 port from  
http://sourceforge.net/projects/ezwinports/files/groff-1.21-w32-bin.zip/download.
I did this, but now have a different error.  It appears that groff.exe cannot 
access troff.exe as needed.  Following is some dialog.  Can anyone help?  Maybe 
Eli is reading this?
