regsvr32不在Windows 7中注册我的DLL [英] regsvr32 doesn't register my DLL in windows 7

问题描述

我在c ++中使用"DllRegisterServer"功能.当我在cmd"regsvr32 MyDll.dll"中使用时，我总是收到一条消息，说明操作成功，但是实际上dll文件未在注册表中注册.它仅在Windows7中发生.知道为什么吗?

I use "DllRegisterServer" function in c++. When I use in cmd "regsvr32 MyDll.dll", I always get a message that action succeeded, but actually the dll file was not registered in registry. It happens only in Windows7. Any idea why? Thanks!

推荐答案

最有可能的是，注册表虚拟化:该DLL不是在HKLM下而是为当前用户在虚拟HKLM密钥"下注册. /> 尝试以管理员身份打开CMD窗口，然后从那里运行REGSVR32.

如果不是这样，则可能是32/64问题.当您从.NET客户端使用COM Interop时，这些情况很常见.
如果COM服务器DLL是32位DLL，并且.NET客户端被编译为任何CPU"，则该客户端将在64位计算机中作为64位进程运行，并且找不到32位DLL.
您可以使用任务管理器"查明是否是这种情况.
如果是这种情况，请尝试将.NET客户端编译为仅32位应用程序.

Most likely, registry virtualization: instead of under HKLM, the DLL is registered under a ''virtual HKLM Key'' for the current user.
Try opening a CMD window as an administrator, and running REGSVR32 from there.

If this is not it, it may be a 32/64 issue. Those are frequent when you use COM Interop from a .NET client.
If the COM server DLL is a 32-bit DLL, and the .NET client is compiled as ''any CPU'', the client will run as a 64-bit process in a 64-bit machine, and it will not find the 32-bit DLL.
You can find out whether this is the case using Task Manager.
If this is your case, try compiling the .NET client as a 32-bit only application.

Hope this helps,
