我必须首先说我是一个编程菜鸟。我不了解 IDE 的所有编译器选项或细微差别，不是很远。但我正在努力自学更多关于本机编程语言的知识。（我对 C# 很满意，但我发现这比 C 容易得多。）
今天，我用C写了这个小程序。它是一个控制台/命令行程序。我使用了 Visual Studio 2012，我的开发机器在 Windows 7 和 8、64 位之间切换。首先，我所做的是创建一个新的 VC++ 项目，然后我选择了一个空白项目。然后我创建了一个新的 app.c 文件。当您在 Windows 资源管理器中浏览文件属性时，我还创建了一个 *.rc 文件来为可执行文件提供一些额外的属性，例如“文件版本”和“公司名称”。然后我转到项目的属性，选择配置属性 -> C/C++ -> 代码生成并将运行时库更改为“多线程 (/MT)，这样我就不必分发 msvcr100.dll 文件连同我的可执行文件。
在 app.c 文件中，我放置了以下代码：
#include <stdio.h>
#include <string.h>
#include <Windows.h>
#include <WtsApi32.h>
#pragma comment(lib, "WtsApi32.lib")
void main(int argc, char *argv[])
{
char *helpMsg = "blah";
char *hostName, *connState = "";
char *addrFamily = "";
HANDLE hHost = NULL;
...stuff and so forth and so on...
}
然后我构建/编译了程序，可执行文件在 Windows 7、8、Server 2008R2、Server 2012 上运行良好，所有 64 位。但是当我尝试在 Server 2003 上运行程序时（我猜也是 WinXP 等），我看到了 Windows 对话框：
“Foo.exe 不是有效的 Win32 应用程序。”
所以我的问题是，我是否缺少一些明显/简单的东西可以让这个可执行文件也可以在我缺少的早期 XP/2003/32bit 平台上工作？我不相信我在我的程序中使用了任何 64 位专有功能。但我认为，因为我确实选择了“空白项目”而不是“Win32 控制台应用程序”，所以我可能会遗漏一些设置。

我也试过去项目属性 - >链接器 - >系统：最低要求版本并将其更改为 5.00 和 1.00 或其他任何内容，但它没有效果。dumpbin.exe 仍将操作系统版本报告为 6.00。我什至在 exe 上使用了 editbin.exe /version 5.00 并且没有报告任何错误……但 dumpbin.exe 仍然报告操作系统版本为 6.00。
