Hello folks,

This bug could be one of those wontfix.
--- quote ---

well, there are also "provide MFC implementation" type tickets which I
personally consider a huge waste of time for any takers.
Arguing with people about the scope of Wine and what are realistic goals is
something I leave for some mailing list.

Refining summary, making it a rather large meta feature request since it's a
framework/collection of various technologies and components.

Seriously taken you would need to add dependencies of many other tickets here
which is not feasible at all.

--- snip ---

Either add a registry key, faking MDAC installation >= 2.70.7713.4 which
obviously can't work at runtime if the app requires MDAC or use 'winetricks -q
mdac27'.

Since 'winetricks' provides an easy workaround, lowing severity.
