So which solution on [3] did you mean for hidden batch file ?

>hide the octave first use dialog 

The vbs file was only ever intended on running from the windows shortcuts or 
from clicking on the file - not for running in scripts where the .bat file 
should be used. The bat file is also the one that is run when octave is called 
in pkg installs etc

The .bat file is installed by default just appears in the bin folder rather 
than at top level so is available if needed. 

But if there is a solution that doesn’t require the .vbs that works then we can 
change it
