Uninstall/Clear IE ActiveX Addon programatically (win32)

Question

I'm trying to clean up the traces left by an ActiveX IE Addon. The Addon (COM DLL) was installed using a cab file.

Manually, IE -> Manage Add-ons -> open the addon and REMOVE is also not helping. It clears the addon from IE but registry traces are left behind! Also, it throws a Runtime Error!

Program: C:\Program Files\Internet Explorer\EInstal.exe

R6034: An application has made an attempt to load the C runtime library incorrectly.

So, I presume the inf file used for installation doesn't have the info to uninstall the addon properly. Am I right? (contents in %alluserappdata%)

What happens internally when an add-on is removed from IE? - Does it use the inf file? Or does it try to call the UnregisterServer call in the registered DLL?

Look forward to your help.

Answer 1

Cleared all the registry entries left behind using Registry funcions.

Couldn't find any other solution. The cab file generated did not have any information in the ini file to uninstall the Add-on.
