Hello jyoung and welcome to the ArtRage forums:)
Not sure why that’s happening for you? I’m on a Mac and the Quick Start guid opens from within AR without issue.
So you might want to tell support about that:

However all the info in the Quick Start guid, and more, can to be found online here: https://www.artrage.com/manuals/getting-started-artrage/
All the info there regarding AR5 is also applicable to AR6.
And enjoy learning about ArtRage 6:cool:
