    Miscellaneous Downloads


    MS-Windows Downloads

    These are cross-built for 32-bit MS-Windows and should run on modern 64-bit MS-Windows systems.


    Linux Downloads

    I have built the system for various "flavors" of Linux. My main development system runs CentOS 5 at present, so the base builds are built under that environment, but I have VMs for other Linux distros.
