MDAC - Download and Repair-Page

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.

  1. Windows XP/2000/Me already contain MDAC by default, but it can get broken under certain circumstances.
  2. Windows 98/NT 4.0 don't contain MDAC by default, so users of these Windows versions must install MDAC first.

You can:
Download and install MDAC
Repair MDAC (if it is already installed, but broken)


1. Install most recent MDAC Version

You can download the English version from our site and other languages at the Microsoft Website (Click the 2nd link).
