Having trouble figuring out which parts of MDAC you have installed or whether some components are missing files or are broken? You're not alone. But here's some good news: Microsoft recently released a tool called Component Checker to help you verify your installed version of MDAC.

Component Checker runs on Windows 2000 (Win2K), Windows NT 4.0, and Windows 9x. You can download the tool at
