Help needed testing automatic win64 configuration

[Brad Anderson]

There are some pending pull requests[1][2] to get automatic win64 
configuration during installation working.  I've prepared a dmd 
2.064-beta installer which includes these unmerged changes which 
you can download here:

http://gnuk.net/dmd-2.064-beta-new-sc.ini.exe


It downloads a slightly modified dmd2beta.zip from 
http://gnuk.net/dmd2beta.zip (my own server) because the 
installer requires some changes to sc.ini that the latest beta 
zip has not included (see 
http://d.puremagic.com/issues/show_bug.cgi?id=11266 ).

This installer also includes support for automatically 
downloading the Visual D installer and running it (another yet to 
be merged pull request[3]).

What I need is help testing it.  I only have the means to test on 
VC2010/SDK 7.0a at the moment. If you have any combination of 
VC2012 or VC2013 and Windows SDK 7.1, 8.0, or 8.1 it would help 
if you could try out this installer and test out building a 
simple 64-bit program (e.g., dmd -m64 helloworld.d) and reply 
here on whether or not it worked. Thanks.
