0x80029C4A - 000208D5-0000-0000-C000-000000000046 0 TYPE_E_CANTLOADLIBRARY - How to fix

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 Office from Control Panel and it should resolve the issue.

Looks like it's often caused by an Office update.
