Error message: Connection manager “Excel Connection Manager” – Hresult: 0x80040154 Description: “Class not registered” – for 64 bit Windows

We have a tested SSIS Package. Somehow it failed during deployment. So the package was reopened using SQL Server Business Intelligence Development Studio. The long message as below was displayed on the output window.

Error: 0xC0202009 at Package1, Connection manager "Excel Connection Manager": An OLE DB error has occurred. Error code: 0x80040154. An OLE DB record is available. Source: "Microsoft OLE DB Service Components" Hresult: 0x80040154 Description: "Class not registered".

Hence, I have searched the Internet and gotten the closest link!996308EF3A99432B!288.entry. The link is accurate. In order to run the SSIS package with the OLE DB driver for Excel, right click the Solution -> Properties then choose Debugging under the Configuration Properties. Choose False for Run64BitRuntime on Debug Options.


By doing this the project should run in the Development Studio. However, the developer cannot run the package using Development Studio for deployment.

When installing 64 bit Microsoft SQL Server, the installation will create 2 DTExec.exe one is located at C:Program Files (x86)Microsoft SQL Server100DTSBinn and another at C:Program FilesMicrosoft SQL Server100DTSBinn (this is based on SQL 2008 and provided your installation folder for SQL 2008 is drive C). Use the DTExec.exe at C:Program Files (x86)Microsoft SQL Server100DTSBinn to execute the SSIS Package.
