"Error loading type library/DLL" while creating Office sections in E-Notebook


The following error message may occur when trying to create e.g. an Excel section in E-Notebook on Windows 10 and MS Office 365:

"Error Initializing Field MS Excel Spreadsheet: Unable to cast COM object of type 'Microsoft.Office.Interop.Excel.ApplicationClass' to interface type 'Microsoft.Office.Interop.Excel._Application'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000208D5-0000-0000-C000-000000000046}' failed due to the following error: Error loading type library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY))."


Repair MS Office installation.
