Currently, Autopackage only supports 64 bit systems that have the 32 bit compatibility libraries from their distro installed.

To install these, use your distributions package manager and search for packages named ia32, compat or similar. The description should be something similar to "Compatibility libraries for 64bit systems to allow 32bit programs to run".

Ubuntu/Debian

Use Synaptics Package Manager from the System->Administration and then search for and install the following packages:

• ia32-libs (this contains the core libraries, including some X11 libs)
• TODO: Fill in more packages if they are needed

Also see the 64 vs 32 bit Ubuntu Wiki Page.
