I'm using wine 1.0 rc3 <-- the only version that has worked for me on Garena. I've tried the newest wine 1.1.36, earlier I've tried wine 1.1.32 for my CPU architecture and it doesn't start Garena at all (no problem with war3.exe on neither version). I've got wine 1.0rc3 using "zypper in wine" (SUSE command for apt-get or yum or else...)
