This pops up when I try with wine:Since it's made for Windows, there's no guarantee it will work in Linux. Cross your fingers. Try installing WINE then install the Windows version of Steam and download and install CS:GO. Then install Esportal and see what happens. FYI, WINE (stands for Wine Is Not Emulation), is basically a Windows layer that runs when a Windows application is called. There are other Windows layer programs you can try. PlayonLinux works well. They use WINE and have install scripts for many Windows programs. They also allow you to have multiple versions of WINE installed and can use a different one for each application you run if each runs better on a different version.
