Hello,

follow-up bug from bug 26028.
If that bug is fixed, the ActiveX control crashes the same way as the installer
here.
The problem lies apparently in AtlModuleRegisterWndClassInfoA/W().

AtlModuleExtractCreateWndData() should never get called twice here (the app
doesn't expect this).

In first call of app window proc (WM_NCCREATE), the app retrieves its instance
data data through AtlModuleExtractCreateWndData().
The app then does some initialization (members, thunk) and sets a new window
proc SetWindowLongW().
The actual work is delegated back by calling the old (prev) window proc of
though CallWindowProcW().
The problem: the old window proc (prev member) is the _same_ app window proc
which was called for window creation (WM_NCCREATE) - and this is wrong.
The default window must be called in this case, not the app supplied one.

--- snip dlls/atl/atl_main.c ---
ATOM WINAPI AtlModuleRegisterWndClassInfoA(_ATL_MODULEA *pm, _ATL_WNDCLASSINFOA
*wci, WNDPROC *pProc)
{
    ATOM atom;

    FIXME("%p %p %p semi-stub\n", pm, wci, pProc);

    atom = wci->m_atom;
    if (!atom)
    {
... 
    }

    *pProc = wci->pWndProc;

    TRACE("returning 0x%04x\n", atom);
    return atom;
}
--- snip dlls/atl/atl_main.c ---

You need to check for superclassed case (e.g. _ATL_WNDCLASSINFO member ->
m_lpszOrigName != NULL) before returning a new window proc in out param,
effectively replacing the default one in app wnd data.

You need to fix AtlModuleRegisterWndClassInfoW() for the installer here and
AtlModuleRegisterWndClassInfoA() for the app in bug 26028
They will both successfully start then without any native override.
