XP SP2 contains an MDAC that is later than MDAC 2.8sp1. Therefore, you cannot directly download the latest version of MDAC 2.8sp1 on the Internet.
My method is: Go to C:/Windows/INF, find MDAC. inf, right-click "Install", and in the pop-up file location box, locate the following directory to find the corresponding file.
C:/program files/common files/system/MSADC
