Re: How to revert from MDAC 2.8 to 2.7?

Hi,

That article, which point to the rollback, should work with MDAC 2.8 as
well. If clients have W2K, then they should have at least MDAC 2.6 installed
on it previously. Hard to say if MDAC 2.7 was installed or not. But
sometimes rollback does not work as expected and you should be prepared to
face some issues here. What these PC do? Maybe you could change the way your
application works with the data to speed it up?
