After much searching I was able to find a piece of freeware that works. It's called System Scheduler. Per the company:
"With the free version, you can have the Window Watcher feature to run at 5pm, and set the Window Watcher to close the application. This does a normal close - not a Kill.
With the Professional version there are more options for closing programs, in the Run Application - Advanced tab there is an option to close the application after x minutes. You can download a 30 day evaluation from our website if you want to give it a try."
Thank you to all who tried to assist with what I needed.
