I decided to exclude the Help from the installer because the Help is the biggest chunk of the installer size. We were adding Simplified Chinese and Traditional Chinese versions of Help, and we were concerned about the size of the installer getting even bigger.
Since we removed all the help files (English, Japanese, and Korean) from the installer, the installer size became as almost half as the previous version. The installer size was 9,526 KB for v15.1.7 (32-bit), but it became 5,620 KB for v15.2.0.
This reduced size will benefit all the Internet users. We were also paying for the bandwidth needed for downloads. Once you install the Help, you don’t need to update the Help as often as the core program.
However, I understand your voice, and I made the download link more visible. Once you install a help, you can also update the help form the Help menu – Check Updates.
