I tried to fix this upgrade problem,
by 1st attempting to upgrade to MDAC 2.8, not only did this not work, but
when it failed , it showed that all the installed files were rolled back.
Even so, damage had been done. Attempting to get a handle on this I used the
MS MDAC Utility Version Checker, it showed that I had MDAC 2.8 RTM version,
but MS Update showed that the upgrade still needed to be performed. Also,
the Utility Checker does not uninstall as it's rumored to be able to.

I found that my cpl add/remove applet no longer functioned properly, and I
got a bunch of error messages when I rebooted Safe Mode. It seems that MDAC,
ODBC , ADO and OLE are all tied in together, and that some important MS
functions are impaired if this is not functioning right, I felt necessary to
push on.

I next downloaded MDAC 2.5 , thinking that a reinstall would solve the
problem.
It did not. Error messages in the installer informed me that MDAC 2.5 was
already installed.

Googling for solutions to the add/remove malfunction, I saw that someone
suggested upgrading to MDAC 2.6. I tried this and it worked.

Yesterday [when I did all this] was a discouraging day, but now the patch
KB927779, causing the original problem is no longer needed. I wonder why MS
didn't put more install warnings and instructions on the download pages for
MDAC.
