I tried to install BGII enhanced edition downloading the launcher from the website, but the launcher does not start.
It says: "It looks like you are unable to write to the current location. Please copy the game to your Applications Directory, or some other writeable location".
I tried to install it on the Applications folder and on my user Application folder, as well as in the desktop but the same message is always displayed. I suspect there is an issue with the permissions in the new version of Mac OS.
I am running the latest version Mac OS 10.12
The Siege of Dragonspear that I had already installed updated without problems instead.
