"dirhtml.exe" "BUILD_~1.INI"
REM "dirhtml.exe" "build_htmlbat.init"
and
Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.run("""dirhtml.exe"" ""build_htmlbat.init""")
The init file does exist.
In a separate trial, I tried removing the INI file reference, and it
did successfully launch dirhtml.
