    Launcher doesn't run on 64bit yet. Wait for that to be released.

    i don't see any reason for a launcher to run in 64bit

    I think it's so that Minecraft would actually run on 64bit Java.

    0.2.1 launcher(exe) seems to run it in 64bit for me. The 0.1.1 jarfile runs it in 32bit unless I invoke it manually using command line. I'm too lazy to write a bat file to do it for me.

    c:\Program Files\Java\jre7\bin>javaw.exe -Xmx4096M -Xincgc -jar D:\Downloads\Feed_The_Beast_Launcher_Beta_v0.1.1.jar
