Will not install. IE closed but doesn't recognize that it is closed

[brainfart]

I close IE as they ask and confirm it under task manager.  However it will not install and keeps telling me that I need to close all IE windows.

How do I solve this

Thanks

Closing the window and terminating the process aren't necessarily the same thing.
