If you install the downloaded version of Microsoft Data Access Components (MDAC) version 2.8 to a Microsoft Windows XP Service Pack 2-based computer, you receive one of the following error messages:
This version is incompatible with the version you are attempting to install.
This setup does not support installing on this operating system.
MDAC 2.8 RTM is incompatible with this version of Windows. All of its features are currently part of Windows.
This issue occurs because Windows XP Service Pack 2 (SP2) installs MDAC 2.8 Service Pack 1 (SP1). MDAC 2.8 with SP1 updates MDAC to version 2.81. You cannot install MDAC 2.8 if the computer is already running MDAC 2.81.
To resolve this issue, use one of the following methods.
Method 1: Install MDAC 2.8 SP1
