Hi,
I just installed Octave 4.4.1 on Windows 7.
I double-clicked on the octave-gui.exe file and after putting up the DOS window the program crashed before the GUI was displayed. This was consistent. I tried re-booting the PC, it made no difference.
I installed 4.0.0 some years ago on the same PC. I haven't used it much but the GUI always started with no problems.
I am interested in providing some extra functionality to the Octave Symbolic package so I decided to update the version of Octave.
Regards,
John
