My OS is Ubuntu 16.04.2 LTS - fully up to date.
I upgraded my NVIDIA driver to ( 384 ) and wine ( 2.13 ) and winetricks ( current git version ) followed the instructions.
Basically I can login and but I don't see Horizons ( because wine is set to 32bit and Horizons is 64bit only now? )
After following your instructions using wine-staging 2.15 on ubuntu 16.04.2 I got error of missing mscoree.dll when launching edlauncher.
PS. There is few typos in the instructions.
