Is the issue present on 4.0.2?

So it may be during the process of running octave from within the installer.

When I renamed .config and ran the Octave GUI, it took me through a couple of introductory screens and started normally.

Bug #40444 bears some relation to this bug

WHat happens if you delete (or rename) the .config folder and run octave?

Now you are leading me into "less certain" territory.

I think .config may have been there, but if it was, I am thinking it was probably empty. I am pretty sure there was no octave folder in there.

I have never really understood Windows file permissions, but I am thinking it may be possible to have the rights to create a folder, but then not have the rights to put anything in it. That's what I think was the case before I recursively added myself to the permission list of all of the folders, but I'm only, say, 80% sure.

I don't seem to have this problem with other usernames' \Documents and Settings\ folders on this machine, even as myself (with admin rights). If I did see the same issue (in terms of lacking permissions), I'd try to confirm this state of affairs.

Sorry to be a bit vague at this point...

Had it created the .config folder and the octave/4.0.0 directory inside?

I am virtually certain I did not uncheck anything in the install process and that therefore it tried to run the application the first time from the installer, and crashed. Every time I subsequently tried to run the GUI, the same sequence of one or two dialogs happened, followed by the crash.

When I went looking for qt-settings they weren't there. Perhaps an attempt to create default settings failed (silently?).

By the time I re-installed, I had fixed the permissions problem.

I suppose there may be two questions: 1. does absence or inaccessibility of qt-settings lead to a crash; and 2. does it silently fail to create qt-settings if it does not have permission?

Just my 2 cents...

Did you run octave for the first time through the end of the installer, or did you uncheck the run octave option and then run it after closing the installer?

Permissions problem with .config folder in Documents and Settings...

Gave myself permission, Uninstalled / reinstalled, and it starts OK.

I have gotten around this but the crash should be fixed.

Windows XP SP3 32 bit, Lenovo R60e.

After the "Welcome to Octave sequence" upon pressing Finish button, Octave crashes with access violation fault, PC=016504E1, EAX=0

Starting from commandline with --force-gui reproduces the bug exactly.

CLI runs OK.

Looking at bug #45459 I see the advice to delete qt-settings but none seem to be currently present.
