@BoRRoZ Yes, it is/was. Uninstalled two java versions and reinstalled the offline downloada version 8.161 64bit version and installed. The gui now shows up and detects: RN2483 1.0.1 Dec 15 2015 09:38:09 created. Hopefully the update will now work. Thanks…
update: it worked, now I have: RN2483 1.0.3 Mar 22 2017 06:00:09 created
