This issue can be resolved by doing one of the following:


 * Reinstall Microsoft Access 7.0. If the Dao2532.tlb file exists, rename or delete the file before reinstalling Microsoft Access 7.0.
 * Use the file Regsvr32.exe to reregister the .dll files. Regsvr32.exe is an application that is used to register dynamic-link libraries (DLLs) and ActiveX controls in the Microsoft Windows 95 and Microsoft Windows NT registries. You can use this file to eliminate the issue of mismatched .dll files.

To reregister your .dll files using Regsvr32.exe do the following:


 * 1) Verify that the Regsvr32.exe file is in your Windows\System folder.
 * 2) Click the Start button, and then click Run.
 * 3) In the Open box, type the following:

Regsvr32 c:\progra~1\common~1\micros~1\dao\dao3032.dll

For information about how to obtain this file, please see the following article in the Microsoft Knowledge Base:
