Thank you for the hint but I still can't get it to run.

I'm afraid there might be a bug in cygwin's w32-shell-execute because
under system-type = windows-nt (26.3) I'm able to start the following
application (with a space in the path).  But under system-type = cygwin
(27.0.50) it isn't finding the exec:

    (w32-shell-execute
     ;; "Open" (concat "\"" (cygwin-convert-file-name-to-windows
     ;;                                      apdl-ansys-help-program) "\"") )
     ;; "open" (concat "\"" (cygwin-convert-file-name-to-windows
     ;;                                      "/cygdrive/c/CAx/App/ANSYS 
Inc/v201/commonfiles/help/HelpViewer/ANSYSHelpViewer.exe") "\""))
        "Open" (concat "\""
                       "C:\\CAx\\App\\ANSYS 
Inc\\v201\\commonfiles\\help\\HelpViewer\\ANSYSHelpViewer.exe" "\""))

Thank you
