SAP Excel upload exception occured

Upload operation failed: Error during Maintain operation: Unable to cast COM object of type 'System._ComObject' to interface type 'Microsoft.Office.Interop.Excel._Workbook'.

This operation failed because the QueryInterface call on the COM component for the interface with IID '{000208DA-0000-0000-C000-000000000046}' failed due to the following error. Error loading library/DLL (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY)).

This message appears during uploading Excel by using SAP Excel Plugin

How can I solved this error ?

Remarks:

Office 2010 Home and Business edition SP2

SAP Business ByDesign Add-in for Microsoft Excel 2010 Version: 135.0.2990.946

    Hello Raymond,

    This KBA could help: 2145890 - Error "Unable to cast COM object of type" in Outlook Add-in

    It is for Outlook but the message is similar and should work for Excel as well.

    Best Regards,
    Gustavo Muñoz
