Elie, Brother Samuel,

With the Windows Gregorio installer, does gregorio.exe only get installed to its own program folder?
My gregorio folder is c:\texlive\gregorio
and I find gregorio in there at:
C:\texlive\gregorio\gregorio.exe

But I also find it here: /c:\texlive\2013\bin\win32\gregorio.exe/

Now, when I ran the Gregorio installer for 2.4.2, it seems to have updated gregorio in the texlive bin folder. Judging from the file dates, I can see that the old version that was at /C:\texlive\gregorio\gregorio.exe/ was updated on March 5, 2015 when I ran the Gregorio Installer the other day (it's creation date was 6/8/2013 but the modification date is 3/5/2015 which indicates it's replacement). The other copy in /c:\texlive\2013\bin\win32\gregorio.exe/ was created for the first time there.

/(By the way, neither gregorio.exe has the proper executable file version information, which it *should* have. I've attached screenshots of the file information for gregorio from both locations, and the file information for my greg program so you can see what I mean.)/


Reason I'm asking all this is because I'm working on my "greg" program <http://www.sspxusa.org/goodies/#greg> which, if you don't remember, I have made to manage gregorio and lualatex for compiling scores - it's a sort of GUI for gregorio.

I want to create a wizard that will discover the full file paths to lualatex and gregorio; so since I have gregorio in two places, I need to know which one to use or look for.

Also, when gregorio is installed, does it add itself to the Windows Environmental PATH? On my computer, the path for texliveis set, and gregorio is found there because it's in a directory on that path.
But I can't remember if texlive created that or if I did.

So:

1. Where does the Windows Gregorio installer place
   gregorio.exe?
2. /Should /there be a gregorio.exe in Gregorio's
   application folder?
3. Does the Gregorio installer add itself to the Windows
   PATH variable?
4. What does the Gregorio installer do if texlive is not
   already on the PATH variable?  That is, where does it
   put gregorio.exe then?
5. Would it make any difference whether the Gregorio is
   used from its program directory as opposed the texlive
   bin directory?
6. Could I trouble you all to add the file-information
   (executable's metadata) for the executable?

Thanks for taking the trouble for me!
