SSIS Error: The requested OLE DB provider Microsoft.Jet.OLEDB.4.0 is not registered. If the 64-bit driver is not installed, run the package in 32-bit mode.

I have a SSIS solution that reads from an Excel file. I recently deployed it to a different server and tried executing it from Visual Studio. I got the following error:

[Excel Source [2]] Error: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "Excel Connection Manager" failed with error code 0xC0209303. There may be error messages posted before this with more information on why the AcquireConnection method call failed.

[Connection manager "Excel Connection Manager"] Error: The requested OLE DB provider Microsoft.Jet.OLEDB.4.0 is not registered. If the 64-bit driver is not installed, run the package in 32-bit mode. Error code: 0x00000000. An OLE DB record is available. Source: "Microsoft OLE DB Service Components" Hresult: 0x80040154 Description: "Class not registered".

Solution

As the error message suggests you need to run the package in the 32-bit mode. To do that:

1. Right-click your solution
2. Click 'Properties'
3. Select 'Debugging' node
4. Set 'Run64BitRuntime' property to False
5. Save and re-run your solution
