Uninstall WM DRM Active-X control

I am using WM DRM to protect content. Licenses for the content are issued through a web page (lauched from within Windows Media Player) using an embedded active-X control with the following Id.

clsid:A9FC132B-096D-460B-B7D5-1DB0FAE0C062

Obviously, not everyon开发者_如何学Goe has access/permission to install the Active-X control so there is a separate process for people in such a position. When the page first opens it detect if the Active-X control is installed and presents the appropriate option to the user. (THe embedded browser control prompts to install the Active-X control if not already done.)

The issue I have is, having previously allowed installation of the Active-X control I can now find no way to uninstall the control. I want to be able to uninstall it to make it simpler to test both forms of license delivery.

The control is not listed in the installed add-ons for Internet Explorer, nor in the 'add or remove programs' list (including updates & windows components). There is an entry for the CLSID in the registry (HKLM\CLSID{A9FC132B-096D-460B-B7D5-1DB0FAE0C062}) but I'm not sure about how to use this to "uninstall" it.

How can I uninstall this Active-X control?

If the control is a dll, this might work:

regsvr32 drmdllname.dll /u
