First you navigate to: C:\Windows\inf and find mdac.inf, right-click on this, select Install from your context menu. The install process starts, and a moment later it will ask for Windows XP SP2 installation CD. Click Browse and navigate to your drive letter, corresponding to your CD/DVD, open the I386 folder, (example: E:\I386).....click OPEN, then OK..... and you're done.

Works like a charm:)
