Hello,

now that's some progress ;-)
With sfc corrected and AJ's addition of updspapi.dll is looks a lot better.

Actually I didn't even think about adding updspapi.dll to Wine because it's
neither documented in MSDN nor part of any (P)SDK hence my initial suggestion
to leave that private M$ stuff alone (SEH)...
Now I see the elegance of the solution but this also requires more work on
setupapi.
I'm sure you are already busy fixing setupapi :-)

In the meantime I provide another bugfix.
In my analysis of the missing catroot folder/file problem (comment #8) I was a
bit puzzled of that unusual exception handling (see the first trace log there).

It actually turns out the be a bug in Wine msvcrt._except_handler3().

To keep the story short: while looping through the scope table looking for
filter/handlers, the new trylevel index must be taken from previousTryLevel of
the current scope table entry.
This also applies to the call_finally_block case.

E.g. pScopeTable->previousTryLevel should be corrected to
pScopeTable[trylevel].previousTryLevel to have next try block filter/handler
properly evaluated ...

Following shows the trace log with my correction (compare with comment #8
trace):

--- snip ----

The handler now gets properly picked up and the exception is handled fine
(message box).
Unfortunately this means that the accidental "self-healing" of missing catroot
folder/file is gone now. :-|
The xmllite installer will display the message box and abort (which is
correct).

If an addition to Wine install script is not feasible, a winetricks step might
be a way to overcome this problem.
