System-Wide ADO Failure

I'm running VB6 Enterprise on Windows Me. Something strange happened to my
system, where any program that uses ADODB blows up as soon as you try to
instantiate a recordset object. All my projects in VB are affected and even
other programs on my computer also blow up with a Type Mismatch error when I
try to start them.

I tried reinstalling VB6 Enterprise; but during the installation, I got
dozens of error messages about various ADO- and OLE-related DLLs that could
not be registered.

Is there any solution to this problem before I reformat my hard disk?
Thanks.

Reformatting should be a last resort.

Sounds like your MDAC installation got corrupted somehow. Try downloading
MDAC from the following web site and re-installing it. That'll most likely
fix things. If not, download the Component Checker to assist in
troubleshooting what's wrong with the MDAC installation.

BTW, this is really more of a Windows or data access problem. It doesn't
really have anything to do with VB.
