That's a good question so I had to look it up and the Microsoft MSDN says:
Visual Studio installs the 32-bit version of the Common Language Runtime (CLR) on an x86 computer, and both the 32-bit version and the appropriate 64-bit version of the CLR on a 64-bit Windows computer. (Because Visual Studio is a 32-bit application, when it is installed on a 64-bit system, it runs under WOW64.)
We already figured out about WOW64 some time ago:
The SysWOW64 folder (Windows on Windows) is where Windows keeps 32bit copies of applications that might be needed from time to time on your 64bit system (the files may be the same). It makes sense that there might be files with the same name out there so if a 32bit version of a file is needed for some reason that is where Windows can find it. There is no SysWOW64 folder on 32bit systems.
So Visual Studio is still 32-bit but will run on a 64-bit system from the SysWOW64 folder - that is why you are still able to run 32-bit applications on a 64-bit system.

Please check your Operating System.
The answer is 1) you just need to make sure that you target processor is 32bit. You can develop for 32bit machine on a 64bit machine and vice versa.
After some looking around it looks like you must have up to date service packs. Read http://msdn.microsoft.com/en-us/vstudio/aa948853.aspx if you want to know more.
Visual Studio includes both 32-bit and 64-bit compilers and tools.
You can install VS on Windows 7 x64 and develop 32-bit applications without any problems.
(Just don't do something insane like hard-coding "C:\\Program File (x86)\\")
