Which bin file to use for installing the ADLAgent based on my architecture, as there are 3 to choose from:
altiris_adlagent-<version>.i686.bin
altiris_adlagent-<version>.x86_64.bin
altiris_tcsdk_adlagent-<version>.i686.bin
Ghost Solution Suite 3.x
i686 and x86_64 refer to different CPU architectures: i686 is a 32-bit architecture, while x86_64 (also known as AMD64 or x64) is a 64-bit architecture. x86_64 is a 64-bit extension of the x86 architecture and is compatible with both 32-bit and 64-bit software, whereas i686 is limited to 32-bit applications.
With most modern CPU architectures, you will be installing the x86_64 bit version of the installer.
