Help Desk: How do I correct the ActiveX component error #429?

The cause for this failure is that the Dao350.dll file was not properly registered when Microsoft Access 97 was installed. This behavior occurs when you run setup for Microsoft Access 97 or Microsoft Office 97 Professional Edition, and the Dao350.dll file already exists on your hard drive. If the file already exists, the setup program does not reregister the file correctly.

To resolve this issue use Regsvr32.exe to Register the DAO Files Regsvr32.exe is a program that you can use to register dynamic link library (.dll) files or ActiveX Controls in Microsoft Windows 95 or Microsoft Windows NT.

1. You will need to download a tool provided by Microsoft to manually register the DLL. Registration Tool: REGSVR32.EXE You can also read about how to use the tool: Text Instructions for REGSVR32.EXE
2. Once the tool is downloaded use Start>Run  and paste in the command to manually register the DLL:      C:\Regsvr32.exe C:\Windows\System\Dao350.dll

The command assumes that both the regsvr32.exe is in the root folder on your PC and Dao350.dll is in the Windows/System folder. If not you will need to adjust the command to include the paths to the location where you have saved the files.
