How to build 32 bits C++ CLR project in 64 bit OS

Question

My OS is Windows 7, 64 bits.

In Visual Studio, I'm trying to build this C++ CLR project as 32 bits, but after I build it, when I run Dependency Walker on it, every system dll it uses (for example, kernel32) is of 64 bit, thus giving the error "Modules with different CPU types were found".

I've already set the platform option to Win32 (btw, is this right? I expected x86, is Win32 equivalent?).
I also checked that in Linker->Advanced->Target Machine is equal to MachineX86.

Is there anything else I could do to build it targeting 32 bits.

EDIT 1: Since HansPassant questioned the reliability of Dependency Walker, I checked the bitness using corflags. Results are these:

Version   : v4.0.30319
CLR Header: 2.5
PE        : PE32
CorFlags  : 0x10
ILONLY    : 0
32BITREQ  : 0
32BITPREF : 0
Signed    : 0

According to this this answer, apparently the dll is targeting "Any CPU".

I targeted 32 bits already, why is this happening?

Are you using the 32-bit version of Dependency Walker, and not the 64-bit version? — PaulMcKenzie, Apr 01 '14 at 19:20
You'll need to stop using Depends, it has not been maintained in a very long time. It is particularly unsuitable to look at .NET assemblies. — Hans Passant, Apr 01 '14 at 19:22
@PaulMcKenzie I'm using the 64 bit version. Are you saying it does make a difference? — Guido Tarsia, Apr 01 '14 at 20:25
@HansPassant Ok, do you know any alternative to check the bitness of a dll? — Guido Tarsia, Apr 01 '14 at 20:26
Why don't you just debug the code? You'll find out *really* quickly. — Hans Passant, Apr 01 '14 at 20:42
@Erandros - Yes it makes a difference. If your module is 32 bit, then the 64-bit version assumes that the 32-bit module is in error. Use the 32-bit version of Depends to view 32-bit modules. — PaulMcKenzie, Apr 02 '14 at 01:33
