This wiki page is for people who fail to build win64 Harmony in the
same way as for Win32, not intended for people who don't have problem
with it. If you don't see any difference, you don't need to read this
page.

This is not so natural for me, that's why I put it there.
1. I am on a Win64 platform which has JDK installed. No
one/information tells me I should reinstall a 64bit JDK, just like I
didn't reinstall SVN and ANT.
2. With 32-bit JDK, the build failed because the platform architecture
is AMD64, which guided the build script to some incorrect patch for
me.

Yes, but it's only obvious for you. Why should the user know she has
to use MSVC2005? Can't she try with Intel compiler? Or can't she try
to look for "MSVC2007"?

If you didn't meet any issue with it, you don't need to know it. I met
this problem and I know some friends met this problem too. I never
type the long path; instead, I just drag & drop the command.

Yes, please.  I created this wiki page because no one else put the
useful info somewhere. When the information is available somewhere, we
can definitely remove this page.

Where are the "over tons of documents" that can help people to build
Win64 Harmony?

Yes, please. I just volunteered to do what I thought right and useful
to the Harmony community. You can volunteer to do what you think
right. And I never criticize other people's serious contribution
unless my contribution is better.
