What is MDAC, and Do You Need It?

For database access, Time Logger depends on components that are a part of the Windows 98SE, Windows 2000, Windows XP, Windows Vista and Windows 2003 Server operating systems. These components are called "Microsoft Data Access Components," or "MDAC."

You may need to download and install these MDAC files yourself (they are free) if:

You have Windows NT, Windows 95, or an earlier version of Windows 98, or
The MDAC files on your system have been damaged, or
Different Time Logger users have different versions of MDAC on their individual systems.

If you haven't yet downloaded Time Logger, you can find out if your system has the MDAC files necessary to run it by downloading and executing a very small application called canruntimelogger.exe (it is only 132 K in size, and will download in under a minute). Click here to download it.

Checking Your MDAC Files

If you've already got the most recent MDAC files, you may want to check them to see if any are damaged, missing, or incorrect. You can do this with the MDAC Component Checker from Microsoft.

PLEASE NOTE: The MDAC Component Checker has often provided false positives for our customers. It is capable of correctly informing you that there is a problem. However, sometimes it reports that there is no problem, yet when our customers force the re-install of the MDAC it fixes their system.

Installing (or Reinstalling) MDAC Files
(for Windows 98/NT4/Me/2000 [not Windows XP])

There are actually two installation files that you must download. Download the two files, and run each of them on your computer.

Click here to download the MDAC files installer (Version 2.81).

After installing MDAC above, attempt to install (or re-install) the Jet 4.0 files. You will need to read the article below and refer to the directions for your version of Windows.
Click here to download the "Jet Engine" MDAC Component Installer (Version 4.0).

Installing (or Reinstalling) MDAC Files for Windows XP with SP2

NOTE: If you are using Windows XP with SP1 (Service Pack 1) then installing Service Pack 2 will update both the MDAC and Jet 4.0 files.

If you already have Windows XP with SP2 (Service Pack 2) installed, you can follow these directions to re-install the MDAC file.

Background

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 receive 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 for Windows XP with SP2

In Windows Explorer, open the c:\Windows\Inf folder.

NOTE: If you cannot see the c:\Windows\Inf folder, please follow these steps:

a.	Click START, click My Computer, and then click Folder Options on the Tools menu.

c.	Under Advanced settings, click Show hidden files and folders.
