Codeunit 7152 - Unknown Automation Server.Unknown Class

Hi,

When I want to compile Codeunit '7152 - Export Item Analysis View' I get the error 'Could not load the selected type library'.
Under 'C/AL Globals -> Variables' there are existing 'Unknown Automation Server.Unknown Class' subtypes for xlApp, xlWorksheet, xlWorksheet2, xlPivotTable, xlPivotCache, xlRange and xlPivotField.

Does someone know which automation variable that is and how to install/register those Dll's?

Thanks!
