WD: Can't Use Microsoft Access Files (.mdb or DDE) with Word

When you use the Mail Merge or the Insert Database command to obtain data from a Microsoft Access data file, the option for "MS Access Databases (*.mdb)" does not appear in the "Files Of Type" list, and the DDE method of obtaining the data is not available.

In addition, you may receive the following error message:

For Word to show *.mdb files or to use DDE with Microsoft Access, the Microsoft Access program folder must be listed correctly in the Windows Registry Extensions key. A Typical installation of Microsoft Access updates the Win.ini file with extension information, but information in the Win.ini file is not added to the appropriate Registry key in Windows 95.

WORKAROUNDS

Method 1: Add Microsoft Access to the Environment path

1. Start WordPad.
2. On the File menu, click Open.
3. In the File Name box, type c:\autoexec.bat. Click OK.
   1. If the file is not found, click Cancel and type the following
      PATH=<path to Access folder>
      where <path to Access folder> is the location of your Microsoft Access folder. For example:
      PATH=C:\OFFICE\ACCESS
   2. On the File menu, click Exit. When asked if you want to save changes, click Yes.
   3. In the File Name box, type c:\autoexec.bat.
   4. In the Save As Type box, choose "Text Document--MS-DOS Format."
   5. Click OK. Exit WordPad. Skip to step 7.
4. Find the line that begins with PATH.
5. Place the insertion point at the end of this line. Type a semicolon (;) and the path to the Microsoft Access program folder.
6. Save the file and exit WordPad.
7. Restart the computer.

Word should now be able to show *.mdb files and to use DDE.

NOTE: If these steps do not correct the problem, make sure that the database you are trying to connect to in the mail merge main document is in the Access directory or in a directory in the path statement of the Autoexec.bat file.

Method 2: Correct the Registry

For information about how to edit the registry, view the Changing Keys And Values online Help topic in Registry Editor (Regedit.exe). Note that you should make a backup copy of the registry files (System.dat and User.dat) before you edit the registry.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows 95. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

1. Click the Windows Start button and click Run. In the Open box, type Regedit. Click OK.
2. Open HKEY_CURRENT_USER and open the following key:

   Software\Microsoft\Windows\CurrentVersion \Extensions
   					

3. On the Edit menu, point to New, and click String Value.
4. In place of "New Value #1," type MDB and press ENTER. Double-click the word "MDB".
   
   A dialog box appears.
5. Type C:\ACCESS\MSACCESS.EXE ^.MDB and ENTER.
   
   NOTE: This path should reflect the location of Microsoft Access on your computer.
6. On the Edit Menu, click New, and click String Value.
7. In place of "New Value #1," type MDA and press ENTER.
8. Double-click the word "MDA."
9. Type C:\ACCESS\MSACCESS.EXE ^.MDA and press ENTER
   
   NOTE: This path should reflect the location of Microsoft Access on your computer.

The new MDA entry is not required in order for Word to use DDE, but it duplicates information that was in the Win.ini file.
