Ah ok, Thank you, it works now, the version in Extension Warehouse was still the old one, I was downloading the library from there

I am already using the last version of the library 3.5.2, and I uninstalled both Library and Windows settings now and installed them again, and still have the same error

It stopped working on Sketchup 2019, I get the following error:

Error Loading File ams_WindowSettings.rb
