我有使用 cpp COM 对象的 ac# 解决方案。COM 对象和 c# 应用程序都是专门为 64 位系统构建的。当我从 VS 2010 运行时，该解决方案可以正常工作。但是，在我将它安装在不同的系统（64 位）上后，找不到 COM 对象。

我认为这是因为它在安装过程中没有注册，但我似乎在这样做时遇到了麻烦。当我尝试

regsvr32 ComObject.dll

我收到一条错误消息，指出“模块 'ComObject.dll' 无法加载。确保二进制文件存储在指定路径或对其进行调试以检查二进制文件或相关 .DLL 文件是否存在问题。

我从 dll 所在的目录中调用 regsvr32，并且我三次检查名称是否输入正确。我尝试在安装程序中注册它，将 dll 注册开关设置为 vsdrfCOM，并收到警告“无法为名为‘ComObject.dll’的文件创建注册信息。这很可能是因为 dll 是在单独的解决方案中构建并添加的将此解决方案作为资源。

因此，我可以将它安装在我的开发系统上，并且运行良好。我认为这是因为 VS 已经注册了 dll。（目前，该 dll 不是安装程序的一部分，因为它会导致问题，因此我将其复制到调试文件夹中。

有谁知道我可能做错了什么？

附加信息：

根据 David Heffernan 的指示，我以正确的方式运行 Dependency Walker。以下是我收到错误消息“找不到入口点 DllRegisterServer”之前的最后几行。

除了提到 DllRegisterServer 之外，没有特定的错误消息。我确实以管理员身份运行。运行时，模块列表中出现另一个错误：打开文件时出错。该系统找不到指定的路径。这是有道理的，因为它是一个空字符串。这旁边有一个问号，所以我认为它是延迟加载。

我在 regsvr32.exe 上再次运行 Dependency Walker，得到以下错误：

LoadLibraryExW("C:\Program Files\Project\ComObject.dll", 0x0000000000000000, LOAD_WITH_ALTERED_SEARCH_PATH) returned NULL. Error: The specified module could not be found (126).

我还在日志文件的顶部发现了这些错误：

Error: Modules with different CPU types were found.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.

谢谢大家的帮助。

这可能是一个依赖问题。使用 Dependency Walker 解决它。使用 Profile 菜单启动一个进程。运行 regsvr32。指定命令行参数和工作目录。

我的猜测是问题是缺少 MSVC 运行时，但该工具将揭示导致失败的原因。

您需要运行 Dependency Walker 提升，以便注册可以工作。

Windows 经常对是否应该从System32或SysWOW64目录运行应用程序感到困惑。

尝试显式运行 64 位版本regsvr32：

%SystemRoot%\System32\regsvr32.exe ComObject.dll

感谢 David Hefferman 和 WhozCraig；您的信息帮助我开始使用 Dependency Walker，在我弄清楚如何解释它发现的内容后，我可以看到它将被证明是一个强大的工具。它还帮助我找出可能的问题。

最后，我选择了不同的方向。我将 cpp 项目添加到我的主项目中，然后在我的安装程序中使用了输出。这导致它正确注册。我仍然不确定这与运行 regsvr32 有何不同，但无论有什么不同，它都会导致事情开始工作。
