SPC.Spets 21 Posted June 9, 2016 I'm using Arma 3 tools update to have both versions, the Main on Steam and the Dev Branch updated with A3Tools, and as the title say, I can not open Tanoa, it have that purchase problem :/ Share this post Link to post Share on other sites
kylania 567 Posted June 9, 2016 Yup, the general consensus is run Dev Branch on your Steam client since that updates constantly and use GameUpdater to update your main branch the few times you need to if you'll be using both. Share this post Link to post Share on other sites
