How do you invoke Emacs from that installation?

From a shortcut in my startmenu.

Tar= get: "C:\Portable Programs\emacs-26.0.91-x86_64\bin\runemacs.exe"=
Start in: %HOMEPATH%

%HOMEPATH% is set to = \Users\asc
=C2=A0
Are there any other versions of libpng16-16.dll on that system?

I ran the following:
$ find.exe / -name libpng1= 6-16.dll
/cygdrive/c/Portable Programs/emacs-26.0.91-x86_64/bin/libpng16= -16.dll
/cygdrive/c/Portable Programs/inkscape/libpng16-16.dll
/cygdr= ive/c/Program Files/emacs-25.1-x86_64-w64-mingw32/bin/libpng16-16.dll
I found the old C:\Program Files\emacs-25.1-x86_64-w64-mingw32\bin on my = path, removed it and restarted Emacs, verified that it was not listed in (g= etenv "PATH"), but no luck. I still cannot display PNG images.=C2=A0
Does pngfix.exe work (it should be in the same directory as
libpng16-16.dll)?

Yes it does.

$ ./pngfix ../lib/python2.7/idlelib/Icons/idle_16.png
IDAT OK= =C2=A0 maximum 12 12 1070 2064 ../lib/python2.7/idlelib/Icons/idle_16.png <= br>
And finally, what is the value of libpng-version in your Emacs?

libpng-version
10634

Cheers
Alex
