Trial expired and you issued update to block uninstall??

I got my trial expired and started uninstall your software off client machines when realised new update to come to block uninstalling option (and also fire some useless “Why are you leaving” poll). Are you nuts or what ???

I want to uninstall client to, and after select uninstall from webconsole from the device the uninstaller process not start. I have to remove it manually. Please help.

Any help?
