问题
I'd like to configure visual studio 2005 to copy .dll's based on whether the OS is 64-bit or 32-bit during a build.
I do not want to specify what the platform target is.
My first attempt was to use a batch file to lookup the Windows version, but some 32-bit and 64-bit versions of Windows share the same version number.
Anyone know of any way to check this?
Thanks!

You should be able to read the environment variable %PROCESSOR_ARCHITECTURE%. Here is some great information on it.

Check out isWow64, I think that shopuld give you what you are after.
Determines whether the specified process is running under WOW64.

Jon's link is a total hack because it relies upon no new processor architectures being added.
See: http://support.microsoft.com/kb/556009 for the "official" batch file method.
