I am trying to uninstall the zfd agent 7 sp1 hp7 from my windows xp machines. Some remove fine running the msi , some machines I have to login as worktation only to remove it with the msi and one machine will not remove at all. I have disconnected it from the network stopped firewall and av. It gets as far as deleting services and then I get the message installation interupted, changes have not been made. I had this on a few machines and got round it by logging in as workstation only.
