Installed Odin on 2018.2.0b2 (64) Windows 10 Getting started does not open any example scenes (projects). Received the following warning: "Unable to open Assets/Plugins/Sirenix/Demos/Sample - RPG Editor.unitypackage: Check external application preferences." First, unclear what external application preferences to check. Second, I don't see anything that sticks out in Odin Preferences or Unity Preferences.
Issue #327 open
