Symptoms

When you open your database in Access, you receive the following error message:

Method 'Connection' of object '_Current Project' failed.

This failure occurs when the VBA Application.CurrentProject.Connection or Application.CurrentDB.Connection is called.

Cause

The Access Database Engine/Access Connectivity Engine (ACE) is included with a number of products other than Microsoft Access such as Microsoft Visio and Microsoft Project. If you install a version of ACE that's different than that of Access, the ACEOLEDB.DLL path in the registry may not point to the corresponding ACE version.

Resolution

You should be able to resolve this issue by running a repair of the Office or Access installation.

Alternatively, you can modify the registry key changing the dll path to match that of your Access version.

Note

Access 2007 - OFFICE12, Access 2010 - OFFICE14, Access 2013 - OFFICE15 and Access 2016 - OFFICE16.
