I have run out of ideas. i have tried all suggestions through looking through your support page to get horizon working. it starts up, horizon logo appears then the program shuts down. When i have task manager open horizon.exe appears on task manager, but then completely disappears. i have team viewer as i need some help with solving this.
EDIT: Horizon open completely fine when not connected to the internet.obviously restricted to offline mode. Also i am running windows 7
