Google Earth Pro 7.3.3.7673 x64 April-2020 Latest version it’s FREE.
The error is: “SketchUp cannot open due to a License error.” along those lines, with not much detail in the dialog box.
I updated from the 2019 version of Google Earth.
Google Earth Pro 7.3.3.7673 x64 April-2020 was running fine only SketchUp 2016 was not opening.
Tried uninstalling other apps, Reinstalling SketchUp but to no avail, then remembered I had installed “Google earth” two days earlier.
Uninstalled it and “SketchUp 2016” was running again.
Just a heads up, see if uninstalling other Google app you have installed besides “SketchUp” solves the problem.
