Windows 7 crash on 8.52a 64bit

[elkYo]

TotalCommander 64bit crashes on Windows 7, no visible log or error message. 32bit works fine.

I used WinDBG to trace the application, looks like there's a stack overflow (see log below).


Any idea?

Code: Select all

(227c.f74): Stack overflow - code c00000fd (first chance)

Do you have any idea what you have done at the moment the crash happens?
Is it reproducible?

[elkYo]

Nothing in particular, I tried this several times after re-installing TotalCommander, including before/after reboot.
It is constantly happening on my computer, I don't know how to reproduce this on other computers.

Well, most likely it's a faulty (crappy) shell extension again, which most notably have problems when right-clicking on files/directories. Search for ShellExView here in the forum to find instructions how to use it to find the shell extension responsible.

Hi,
I don't think it's a shell extension because TotalCommander doesn't even load.. it doesn't show the GUI, no visible output, no log files written to the totalcmd folder... nothing.

Any other ideas?

I also think that it's a shell extension, maybe an icon extractor which crashes when TC tries to load an icon. Please try Shell ExView.

OK, I used Shell ExView and disabled all non-Microsoft extensions.
Still same results - 64bit doesn't run, 32bit runs perfectly fine.

It would've been nice if you'd written such an important fact in the OP.

Check Windows Event Log. There may be some hint in there.

My first idea would be the well-known 'start with a clean ini file' approach.

[elkYo]

Nothing particularly interesting or related to TotalCommander in the Windows event log. I tried reinstalling after cleaning the configuration files (ini file), still 64bit doesn't load and 32bit works fine.

[Dalai]

Your anti-virus software or something like that might prevent TC from launching.

BTW: How can a program crash when it doesn't start at all? Or does it start and just doesn't show any window? Do you see totalcmd64.exe in Task Manager?

Just a silly question, but I have to ask: Is your Windows version 32-bit?

elkYo,
Also, just to make sure, did you use ShellExView to disable 64-bit extensions?

Calls stack? https://msdn.microsoft.com/en-us/library/windows/hardware/ff540620%28v=vs.85%29.aspx

Hi,
The program was showing in Task Manager for 2-4 seconds, and then disappear. I realized it is crashing due to the stack overflow I noticed using WinDBG. I disabled 64bit extensions, still no good.. And yes, my Windows is 64bit

After several re-installation rounds, including registry cleaning (CCleaner), manual registry & file system cleanups and disabling AV software - 64bit now works.

Looks like it was Symantec AV that caused TC 64bit to malfunction.

Thanks for your help!
