Basecamp thinks Google Earth Not installed

I have used Basecamp for planning RV trips for several years. The one feature I like the best is that I can view routes, waypoints, etc in Google Earth. I was able to have Google Earth open in the background and the use View>Google Earth> Selected item to view the route, etc. Now I get the message that Google Earth isn't installed. This just started a couple of months ago. I use a Dell PC with Windows 10. Does anyone know of an issue with a Win 10 update or other problem?
