Description:
(. 1) x86-64 for 64-bit operating system, the x86 for 32-bit operating system;
(2) the embeddable ZIP, Executable Installer, Web-based Installer difference
embeddable zip: a compressed file is downloaded, after decompression setup is complete.
executable installer: download a few MB of exe executable program, offline installation.
web-based installer: zip download is a few MB of exe executable program, you need to install networking.
