You're welcome.
Now that you have Spybot installed okay, if you prefer not to have the Security Center Service installed, you should be able to remove it without getting the same error that you did when installing. If you prefer to uninstall it, you'd open Spybot Start Center as administrator, checkmark Advanced User Mode, click Settings, then select the System Services tab. Under Security Center Service, uncheck Active after every reboot, then click Stop to stop the service, then click the arrow and select Uninstall, then click the Apply and OK buttons to exit.
