MDAC 2.8 RTM is incompatible with this version of windows

[Dale82]

In order for our financial software to work we require MDAC 2.8.
this has installed fine on 9 of the customers machines however just one machine keeps coming back with the error.

MDAC 2.8 RTM is incompatible with this version of windows, all of its features are correctly part of windows.

This then fails, however our software will not install unless this is installed.
Initially i have tracked down that we look for the msado15.dll and sometimes i can replace this with an older version and it will be fine, however not on this occasion, as xp keeps replicating\repairing the file.

Problem machine is XP PRO _ SP2 (same as the rest )

Any guidence/help would be greatly appreciated

Oddly, you sometimes have to install the older component set first, then upgrade:

I would not consider trying to work around the file protection system native to XP in this case.
