Using ADO and installing a VB6.0 application fresh on someones machine causes this error.

This error has occured for me before and it went away, I don't know precisely what fixed it, but now my friend at another company is getting the same thing and we can't figure it out. I know I had upgraded from MDAC 2.0 to MDAC 2.1 (SP2) but I can't verify that this fixed the problem.

Anyone have the same issue that knows what's going on.

Verified: MDAC version, MDAC is installing on the machine from the Setup program, confirmed a reboot.
