I installed MSE on my 3 household computers this week and one of them repeatedly failed to start MSE automatically after a reboot.

Just thought I'd note that Milton.J's solution worked for me. I changed Windows Installer Service from manual to automatic; the other two services mentioned were already set to automatic.
