Unable to remove SAE 3.5 - get Error: 1921

We have SAE 3.5 on client workstations at various patch levels. I have a stubborn Win7x64 box that I can't remove it from Control Panel or via an ePO deployment task: it fails with Error 1921. On same machine, we also have VSE 8.8, ePO, and HIPS.

In the past, I was able to un-install with a command like this:

msiexec.exe /x{C44506FC-B846-4782-AC2B-8C30236CE075} /q

This worked on an earlier patch level SAE but not on later levels. In VSE 8.8, the box in unchecked for "protect McAfee files from being altered."
