AddInSpy is a diagnostic tool that discovers all registered Microsoft Office add-ins on a computer, and then reports as much information as it can about those add-ins. The tool works with all versions of all Microsoft Office applications that support COM add-ins, and all types of COM add-ins.
Original AddInSpy tool was developed by VSTO team in Microsoft.
This source code is based on disassembled version of original AddInSpy.
