Yes (I needed three shells to get emacs-28.0.60 -Q started)

I didn't set INFOPATH (checked ~/.bashrc, I think it isn't a Windows
environment variable).

Please have a look below, in summary: The Info variables are looking
very fishy!

1) Windows command prompt, didn't work

In the installation folder:
runemacs.exe -Q

=> libgmp-10.dll not found

By the way, there was no runemacs.bat in the installation directory

2) MSYS2 MSYS, didn't work either

uidg1626@VSL7V7PW MSYS /d/Emacs/emacs28/bin
$ echo $INFOPATH


$ ./runemacs.exe -Q

=> No Emacs GUI!  No error message, next try:

uidg1626@VSL7V7PW MSYS /d/Emacs/emacs28/bin
$ ./emacs-28.0.60.exe -Q
D:/Emacs/emacs28/bin/emacs-28.0.60.exe: error while loading shared libraries: 
libgmp-10.dll: cannot open shared object file: No such file or directory

=> No Emacs GUI.

3) MSYS2 MinGW 64-bit, is working

uidg1626@VSL7V7PW MINGW64 /d/Emacs/emacs-28/info
$ echo $INFOPATH

changed to the installation folder: /d/Emacs/emacs28/bin
$ ./runemacs.exe -Q

INFOPATH seen by Emacs (before C-h i):
C-u M-! echo $INFOPATH

Info-default-directory-list C-u C-x e ("%emacs_dir%/share/info/")

Then Info: C-h i
=> No emacs menu item in (dir) Top.

Info-directory-list C-u C-x e ("D:\\appl\\MSYS2\\usr\\share\\info")

Thank you
