I have followed both these guides to install Wine and Battle.net on my Elementary OS system, with configuration -
Elementary OS 0.4.1 (Loki) [Built on Ubuntu 16.04.3 LTS]
Intel Core i7-6500U CPU @ 2.50GHz
All goes well until I reach the step where I have to install Battle.net through Wine. I've tried this using both the different commands in these guides -
$ wine64 ~/Downloads/Battle.net-Setup.exe
$ WINEARCH=win32 vblank_mode=0 Downloads/Battle.net-Setup.exe
but they both lead to the same error window -
The program Battle.net-Setup.exe has encountered a serious problem and needs to close. We are sorry for the inconvenience.
