Vista 16-bit compatibility

[Guest]

hi all~

Nice to meet you all. I have some questions on the compatibility.

I know that 16-bit programs are not supported by x64. It that mean both old
DOS and Win-based 16-bit programs (like those in Win3.1)?

Is that x86 can support 16-bit programs to the same extent like XP does?
Like the above question, can it run both DOS and Win-based 16-bit programs?

Finally, I would really like to know if MS has any official announcement on
Vista's 16-bit compatibility?

Could someone answer me ASAP? I would be grateful to have the answer soon as
it's quite urgent.
Thanks very much for helping!

Regards,
Richard

• No 16-bit code can run, except for recognized InstallShield and Acme
installers (these are hard-coded in Wow64 to allow them to work).
• 16-bit Setup bootstraps are not supported.
• 16-bit MS-DOS and Microsoft Windows 3.x utilities will not start. If you
attempt to start such a program, you receive a "Program.exe is not a valid
Win32 application" error message.

Well, both statements above are on MS web pages. Is that an official
announcement?
