Visual C++ 2010: LNK1104, LNK1181 - .obj Files Will Not Auto-Generate

I've recently downloaded 'Microsoft Visual C++ 2010 Express' edition on my 'Windows Vista Home Premium' machine. I'm a Java programmer trying to make the switch to C++, and this is quite discouraging:

  1. I open Visual C++
  2. "File -> New -> Project..."
  3. select "Win32 Application", default, default, default, etc... "Finish"
  4. Right-click solution (or project) -> "Build"
  5. The output window displays,

    ------ Build started: Project: Engine, Configuration: Debug Win32 ------
    LINK : fatal error LNK1104: cannot open file 'Debug\Engine.obj'
    ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
    

I also receive a "LNK1181" error sometimes. The problem is that the compiler can't find these objects, but if I'm not mistaken, the compiler is supposed to auto-generate these .obj files during the compile. I've checked the 'Debug' folder for 'Engine.obj' - it's an empty folder. So, why isn't Visual C++ creating these .obj files? Can someone objectively tell me why Visual C++ will not generate these .obj files please?

As a side note, I have an inkling that this may have to do with my system type (x32 vs x64). I'm pretty sure I'm running 'Windows Vista Home Premium (x32)' on an x64 based piece of hardware. I've had problems with Microsoft Silverlight (Microsoft, of course!) serving me the wrong .exe because the website used my hardware credentials to determine what version was right for my computer. x64 would not install on my machine, but when I go to 'System Info', under 'System Type' it says "x64-based PC". The x32 version later installed just fine. Perhaps there is a compatibility issue with the version of Visual C++ that I was served?

Update: I've tried installing the x64 version of Visual Studio 2010 - Nothing. Same issue.

Go to the following path

project -> properties -> c/c++ -> Generate preprocessed file

just set it as NO

Tried exactly the same on Windows 7 x64 with Visual C++ 2010. Seems ok.

This is what Visual C++ generated for Engine.cpp:

// Engine.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"


int _tmain(int argc, _TCHAR* argv[])
{
    return 0;
}

Here is the build output:

1>------ Build started: Project: Engine, Configuration: Debug Win32 ------
