What is MDAC?
MDAC stands for Microsoft Data Access Components. It is a widely used Windows system component that implements database connectivity features. MDAC is required by many Windows programs that implement database features.
- Windows XP/2000/Me already contain MDAC by default, but it can get broken under certain circumstances.
- Windows 98/NT 4.0 don't contain MDAC by default, so users of these Windows versions must install MDAC first.

How to Repair MDAC 2.81 on Windows XP with SP2
Windows XP with Service Pack 2 contains MDAC version 2.81, which is currently not available for download at the Microsoft Web site as a standalone installation. If you try to install MDAC 2.8, which is the latest available standalone download of MDAC, you will get a message that you already have a newer version of MDAC installed. Therefore, under Windows XP SP2, you must manually repair MDAC 2.81 as outlined below.
How to Repair MDAC 2.81 on Windows XP with SP2
- Open the folder C:\Windows\inf, and locate the file mdac.inf. Note: Your Windows directory could be named differently, e.g. C:\WinXP
- Right-click the file mdac.inf and click Install.
