GeoGebra does not start without internet connection
I have downloaded and installed the lastet Version of GeoGebra Classic 6 (Windows offline installer dowloaded from here https://www.geogebra.org/do...) and run it on a Windows 10, 64bit system.
My problem: If the internet connection is switched on, GeoGebra will start. Otherwise it won't.
I have tried to find any solution on the Internet and also to reinstall GeoGebra, but without any success.
