"Error 1923. Service *** could not be installed. Verify that you have sufficient privileges to install system services", (where *** is the name of the relevant service.)
In each case, in advance of running the downloaded install package, I have removed all traces of previously installed AV software by using the vendors' own removal tools, deleting all the folders created and cleaning the registry using PC Tools Desktop Maestro, CCleaner, Windows Live OneCare (Cleanup module) etc. Still no luck. Every time, I am logged into an Admininstrator account and run the install package as Administrator.
I have turned off User Account Control and tried creating a new Administrator account from which to install. Once only, I successfully installed BitDefender using this method. "Hooray," I thought, "now I have found a workaround for the dreaded Windows Installer error 1923", so I (stupidly) uninstalled BitDefender and tried to reinstall MSE. Since then, I have been unable to install any AV software and am now running a laptop with only Windows Defender (which I of course turn off before trying to install any AV software).
Any ideas? I am at a complete loss and about ready for the padded cell
