Hi there, @walter_yost ...
Doing a quick Google search, this page was the first result which should help you:
How to Update Chrome to the Latest Version - Google Chrome
You might also want to check out What are the browser and computer requirements for Instructure products? because there is a browser check built right into this documentation that will tell you if your browser on your computer is compatible with Canvas. In general, Google Chrome and/or Mozilla Firefox are good browsers to use when navigating around Canvas.
I hope this helps a bit! Sing out if you have any other questions about this...thanks!
