ACC2: How to Remove the MS Jet 2.5 Database Engine

ID: Q124902

The information in this article applies to:

Microsoft Access 2.0

SUMMARY

Moderate: Requires basic macro, coding, and interoperability skills.

This article describes how to remove the Microsoft Jet database engine version 2.5 files that are installed when you install the Microsoft Access version 2.0 Service Pack. The procedure described in this article removes only the Microsoft Jet database engine version 2.5 files. It does not remove the OLE 2.02 files or the ISAM DLLs that are installed with the Service Pack.

For a complete list of files installed by the Service Pack, please see the READSRV.TXT file included with the Service Pack.

MORE INFORMATION

Follow these steps to remove the Microsoft Jet database engine version 2.5 files from a single-user system:

Quit Microsoft Access or any other program that uses the Microsoft Jet database engine (such as Microsoft Visual Basic).

Run the Microsoft file decompression utility DECOMP.EXE. This file is located on Disk 1 of your original Microsoft Access disks. Run the utility with the following command:
```
      DECOMP -f 
```
(The -f parameter causes DECOMP to replace files.)

When you are prompted "Enter the name and/or path for the compressed file" type a filename from the table below and insert the appropriate original Microsoft Access disk in the appropriate disk drive. Note that compressed files have filenames that end with an underscore character (_). So, to decompress the MSAJT200.DLL file, enter
```
      <drive>:\MSAJT200.DL_ 
```
where <drive> is the disk drive containing the original Microsoft Access disk.

When you are prompted ""Enter the name and/or path for the decompressed file" enter the appropriate name and path for the file from the table below. To decompress the MSAJT200.DLL file, enter:
```
      C:\WINDOWS\SYSTEM\MSAJT200.DLL 
```
Note that this example assumes that you have Microsoft Windows installed in the WINDOWS directory on drive C.

Repeat steps 2-4 for each of the files in the following table:


      File Name      Location          Size       Version    Disk
      -------------------------------------------------------------
      MSAJT200.DLL   WINDOWS\SYSTEM    995,056    2.50.1117  Disk 3
      MSAJU200.DLL   MS Access dir      98,032    2.50.1108  Disk 2
      MSJETERR.DLL   WINDOWS\SYSTEM     11,232    2.50.1108  Disk 4
      MSJETINT.DLL   WINDOWS\SYSTEM     15,936    2.50.1108  Disk 4

      NOTE: The file sizes listed in this table apply only to the U.S.
      version of the Service Pack. The file locations apply only to the
      U.S. version of the Service Pack on 1.44 MB disks.

Delete the MSAJU200.DLL file from the WINDOWS\SYSTEM subdirectory.

Restart Microsoft Access.
