你检查过这个显而易见的地方了吗？ DllMain入口点 - Windows应用程序| Microsoft Docs [ ^ ]。

dll的问题通常导致与其他dll的依赖关系，这被称为dll hell。所以欢迎;-)



我建议使用 dependency walker 工具。这个伟大的工具帮助我在很多疯狂的场景中解决了我的头痛。注意x32和x64风格的这个工具（和你的dll）



profi-tip：尽可能经常使用静态链接并检查dll是否在搜索路径或在正确的目录中也应该是进程的起始目录。



咒语是：用户dll在应用程序的安装目录中，但是系统或第三方dll ware随供应商的安装软件一起安装。

Problems with dll are often resulting with dependencies to other dlls, This is known as "dll hell". So welcome ;-)

I would recommand using the tool dependency walker. This great tool helped me in a lot of crazy scenarios and solved my headaches. Pay attention to x32 and x64 flavor of this tools (and your dlls)

profi-tip: using static linking as often as possible and check that the dlls are in the search path or in the correct directory which also should be starting directory of the process.

The mantra is: user dlls are in the installation-directory of the app, but system or third party dlls ware installed with the installation software of the vendor.
