If you try to launch AntConc on an Ubuntu-based 64-bit system, you get the following error message (tested with versions 3.2.4u, 3.3.5u, 3.4.0u and 3.4.1u):

./antconc3.2.4u: No such file or directory
or 
./AntConc: No such file or directory

The minimal dependencies I had to install in order for AntConc to start successfully on Ubuntu 64-bit were the following libraries (tested on Ubuntu 13.10 and Xubuntu 12.04 LTS):

sudo apt-get install libx11-6:i386 libxss1:i386 libxft2:i386
