Use DependencyWalker to check both webkit.exe and Msvcrt.dll for _resetstkoflw.

I'll do that soon.

It appears that Avant browser probably has a rollback for an XP-specific version of Chromium and Vista uses the 7+ version, maybe. It would explain why Windows XP did not give a single error message but Vista had an endless, hysterical cycle that required ending the process tree.

Avant Browser is actually a tri-core browser (much like Lunascape): 

1. It can use the Trident rendering engine of the OS available Internet Explorer version; on fully updated Vista SP2, that would be IE9.
2. It can use Mozilla Firefox (Gecko) rendering engine.
3. It can use Chromium (webkit) rendering engine.

Their downloads page offers choices for fetching the Lite version (Trident engine only) or the Ultimate version, with all 3 engines; that last one is also available in a USB (portable) flavour...

I suspect the version you tested under Vista was the "ultimate" one... As you said, gecko.exe in latest AB build (2019 build 2, 5.18.2019) is of version 66.0.5.7070, based on Quantum 66 code, thus incompatible with Vista (and XP, of course...); if you try to manually launch gecko.exe, you'll get a "not a valid Win32 application". So the Gecko rendering engine CAN'T be used in Vista... :(

The WebKit engine is of version 74.0.3729.131 and, unlike the case of Chinese browsers, isn't patched for XP (and Vista) compatibility; if you try to manually launch webkit.exe under Vista, you get "The procedure entry point TryAcquireSRWLockExclusive could not be located in the dynamic link library KERNEL32.dll"; in other words, that engine too is incompatible with Vista...

From the above one can easily conclude only the Trident engine is usable under Vista; the frontend (GUI) of Avant Browser does run under Vista, but somehow the browser defaults to the Chromium web engine, with the behaviour you reported; but the GUI behind the error pop-ups is still responsive and one can use the Options wizard to set the default RE to IE9 standards:

After that setting, you can properly launch AB under Vista and it will use Trident (IE9), but, and Vista users are already aware, IE9's engine is pretty dismal when it faces the web standards of 2019; our own MSFN Vista subforum is rendered very poorly:

And because webkit.exe is still being called by the AB GUI (for several secondary functions), when you exit AB (even when Trident is the default RE), you're still gonna get webkit related popups, which you'll have to kill via Task Manager... :angry:

Summary: Avant Browser under Vista? A lost cause, TBH; only the Lite version can be installed and properly launched, but I see no real reason to, as you're in essence just getting a "re-skinned" IE9 with all its shortcomings with regards to browsing the web in the year 2019 (and beyond) ... 

:P
