RE: Octave does not start

[David Remans]

Hi Markus,

Here is small recap of the current status, still the GUI does not show:

I uninstalled Octave 6.2.0, and deleted all remaining files and rebooted the 
computer.
I downloaded the installer for Octave 6.3.0 and installed this version 
(installation for all users)
I do have admin rights on my machine.
For antivirus I use default windows defender. I tried all steps below with and 
without deactivating windows defender.

- I can run a general VBA scrip like  "hello world", I can also run this script 
from the Octave directory : C:\Program Files\GNU Octave\Octave-6.3.0
- When I start the GUI from the start menu shortcut, nothing happens
- When I start the GUI from the start menu shortcut as administrator, I get a 
pop-up from windows to allow execution of the octave.vbs --gui script. After I 
allow execution, nothing happends
- When I run Octave.bat in command window, this runs well (see attached 
screenshot), I can create variables etc in command line
- When I use CMD to run the octave.vbs script It seems to run the script (but 
GUI does not open). To test I added a line at the end of the script to show GUI 
MODE, and I get proper output.
- When I open Octave CLI from the start menu a command window opens with only a 
blinking cursor. (see attached screenshot) in the title balk it mentions 
"Octave-gui.exe"
- Using CMD I search for GNU file see attached screenshot for returned info. (I 
also attached the content of the file, changed the extension to .txt to allow 
transfer)

Still no clue as to why the GUI does not show

Best regards,
David

That is good news. So, Octave per se seems to work. But for some reason the GUI 
doesn't start.

Some GUI related packages have been updated in our build system for Windows 
since Octave 6.3.0 has been released. Could you please check if a nightly build 
from octave.space works for you?

So, there might be two unrelated issues here:
1. The GUI doesn't open.
2. The .vbs file doesn't open the CLI.

If I'm not mistaken, you forgot to add the asterisk at the end of the last 
command. Could you please execute the command as shown?

At the installation location that you've shown in the last screenshot, the 
corresponding commands would be:
C:
cd "\Users\d.remans\AppData\Local\Programs"
dir /x GNU*
