my soluton : open the file with 7z or winrar . extract the exe file inside. copy the exe in the arma 3 main dir. create a shortcut of the commun patch file. In shortcut file properties add:
-incurrentfolder
Installed with play with six, but i'm not sure it's completely installed. The game starts without errors but all the mod interface is the same of arma 3 (not iron front interface) Is it correct?
