I am trying to install the QFE from KB2403277.

When I install it I get stuck with a message "Waiting for another install to complete".

I don't have an install in progress.

How can I see what it thinks is the one in progress?

This happens from time to time, I typically see it either when there is a broken install or an update process running. 95% of the time it is a broken installer that hasn't quit.

I would advise launching Task Manager and force any instances of SETUP.EXE or MSIEXEC.EXE to quit.

Hopefully this should help you!
