Did you install for all users (i.e. in "C:\Program Files\...") or for the 
current user only (i.e. in your AppData folder)?
                [DRE] First I installed for all users, now I installed for 
current user only, I get the same behaviour.
Depending on the answer to that question, you'll find an "octave.bat" file at a 
path like this one:
"C:\Program Files\GNU Octave\Octave-6.3.0\mingw64\bin\octave.bat"

Does executing that .bat file (e.g. by double-clicking) open a command line 
interface with an Octave prompt?
                [DRE] Yes this works fine, I get a command Prompt with text in 
it
Additionally, you'll find the .vbs file (that looks like it's not doing the 
right thing for you) at a path similar to this one:
"C:\Program Files\GNU Octave\Octave-6.3.0\octave.vbs"

Does executing that .vbs file directly (instead of through the link in the 
start menu) open the Octave GUI for you?
                [DRE] No it does not solve the problem

Do I understand correctly? You only see a command screen with blinking cursor? 
No text at all?
                [DRE]   Yes I do not see any text on my screen

Some users reported that they had problems when Octave was installed in paths 
containing spaces because short file names were deactivated for them. (IIRC, 
they were able to start Octave though.) Anyway, could you please open a CMD 
prompt, execute the following commands and show what you see? Might need to be 
adapted if Octave was installed to a different location:
C:
cd "\Program Files"
dir /x GNU*
                [DRE] I did, see attached (second) screenshot
