I want to know the answer to the following question:
What is 16-bit support intended for?
All the background I'm provided with is that "The 32-bit version runs on CPUs compatible with x86 architecture 3rd generation (known as IA-32) or newer, and can run 32-bit and 16-bit applications, although 16-bit support must be enabled first.". Is that enough to answer the question?
Answer: no
