VS2010 express on 64Bit windows - can it compile 32bit binaries without the win7 sdk?

i can't find this information anywhere. I know that if you install vs2010 express on a 32bit os you need the win7 sdk to build 64 bit, but is it the same the other way round?

EDIT - I am in开发者_如何学编程terested in the c++ version, but I guess it's probably the same for others

thanks

By default VS2010 Express will only target Win32. It doesn't matter if you are running Win7-64, MSVC++ Express uses the 32-bit tools unless you install the SDK.

From MSDN:

64-bit tools are not available on Visual C++ Express by default. To enable 64-bit tools on Visual C++ Express, install the Windows Software Development Kit (SDK) in addition to Visual C++ Express.

I have been able to successfully build and deploy C# apps from a Win 7 64bit machine onto machines running 32 bit Windows XP, Vista and Win 7 without any extra SDK. So far I have had no issues.
