Help fixing an error

I keep on getting the error

Error loading launcher://unity/C:/Users/matth/AppData/Roaming/Unity/Packages/node_modules/unity-editor-home/dist/index.html?code=KuPchOIajuXrFr1cm8o_ig004f&locale=en&session_state=3f5ad32802ec4a476a3ad29161555ee887f699e42947e1cb2ab6d3fde272a7c2.0RCAe_bNB2iun1mODl3yMw018f#/login

And i do not know why even when i reinstall unity and make new projects that error still comes up how can i fix it?

That issue is about to be fixed on 2017.2 according to unity team. Many people have that error going on, just ignore it.
