I've got a List of COM-AddIns from Excel and want to find out the installation-path of the AddIns, but the object "Microsoft.Office.Core.COMAddIn" only have the following Properties:

Application
Connect
Creator
Description
Guid
Object
Parent
ProgId

And the Property Object is "Nothing/Null".

Is there a way to use the Interop? Or do i use the guid and search in the registry?

  • You mean you are getting the listof Excel COM-Addins through the program, and you need to find its installation path? – HariHaran Jul 13 '12 at 10:30
  • Right. I get the COM-AddIns through the Excel-Interop in VSTO-Project. – Hiead Jul 13 '12 at 10:41
