I've tried to install Starcraft 2, Warcraft 3 and Starcraft Remastered manually (from Battle.net .exe file).
I've an XUbuntu 16.04 64 bits and last version of Playonlinux.
Playonlinux logs always shows only following error:
...
fixme:wininet:InternetSetOptionW Option 77 STUB
err:wininet:open_http_connection create_netconn failed: 12029

Anybody could help me?
