AddInSpy

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.

Features

AddInSpy is a standalone WPF application. AddInSpy is a simple front-end for the AddInScanEngine.dll – this DLL contains all the main scanning functionality.

The scan engine scans the registry for Office add-ins, and reports the following details:

• Whether the host application is running, and whether the add-in is loaded.
• The type of each add-in: VSTO, managed non-VSTO, native.
• FriendlyName, ProgID, CLSID and LoadBehavior of the add-in.
• Manifest path, assembly path, and assembly strong name.
• Registry hive (HKCU or HKLM) where the add-in is registered.
• CLR version the add-in was built against.
• VSTO runtime version used by the add-in.
• Installed date, and publish version.
• Which extensibility interfaces the add-in implements for Ribbon, custom taskpane, etc (including via VSTO wrappers).
• Whether the add-in exposes itself for automation through the COMAddIns collection of the Office host application.
• Whether the add-in is in the disabled items list for the current user, for each selected Office host application.
• Whether the add-in is registered as the provider for any custom form regions.
• Context information: machine name, user/domain name, OS details, VSTO environment variables.

Reports can be displayed in a grid on-screen and can also be logged to an XML file for printing.
