To install the entire DualShield Authentication platform or some of its components, download the installation file setupdualshieldxxx.bin in which xxx is the version & build number, e.g. setupdualshield64-5.7.1.0930.bin.
However the downloaded installation file is not executable, you need to use root account to execute command chmod in order to change the privilege, e.g. chmod a+x setupdualshield64-5.7.1.0930.bin
