I'm installing Cisco Secure Desktop (CSD) for a customer and needed to re-test the installation process. Within internet explorer's (IE Version 7 & 8 ) managed add-on feature, I noticed that the CSD ActiveX Control doesn't have an uninstall feature.

To remove the control I had to close IE, browse to...

C:\Windows\Downloaded Program Files

..and remove the following files..

CSDWebInstaller.inf
CSDWebInstaller.ocx

When re-starting IE the control was gone and I could test the re-install, I hope this helps some other googler! :cool:
