CoCreateInstance返回-2147221164？

[GK_2014]

先贴代码吧：

 	
const CLSID CDOMDocument40Class::m_ClsId = {0x88d969c0, 0xf192, 0x11d4, {0xa6, 0x5f, 0x00, 0x40, 0x96, 0x32, 0x51, 0xe5}};
IXMLDOMDocument2 *p = NULL;
	HRESULT hr = CoInitialize(NULL);    //初始化COM
    if (SUCCEEDED(hr))    {
 	  hr = CoCreateInstance(m_ClsId, NULL, CLSCTX_ALL, __uuidof(IXMLDOMDocument2), (LPVOID*)&p);
 	  if (hr != S_OK) 
		  AfxThrowComException(hr);
	}
 	else	{
          AfxThrowComException(hr);
	}

在我电脑上可以创建组件，换了好几台其他电脑，函数CoCreateInstance返回-2147221164，注册表找不到m_ClsId 。是不是系统设置的问题？

http://blog.csdn.net/huigll/article/details/1459765 还有要给给msbn3.dll注册 参考下下面的代码： CComPtr<IMMTGenerator> tGenerator; const IID IID_IMMTGENERATOR = {0xC753602D,0x67AA,0x4B91,{0x97,0xD3,0x19,0xA7,0xE6,0x34,0x0D,0x70}}; CLSID clsid; hr = CLSIDFromProgID( L"Generator.MMTGenerator" , &clsid ); if(FAILED(hr)) { AfxMessageBox("Error: CLSIDFromProgID([Generator.MMTGenerator])");// return; } hr = CoCreateInstance (clsid, 0, CLSCTX_INPROC_SERVER, IID_IMMTGENERATOR, (void**)&tGenerator); if (SUCCEEDED(hr)) { }

对应的控件要到其他机器上先注册，regsvr32

Your control is not registered correctly. The "Logged On User" -- usually the anonymous account -- does not have adequate permissions to run the control. In many cases the anonymous login account (IUSR_<machine>) does not have appropriate permissions on certain Directories/Files or the specific component and its dependencies. While less frequent, if the registry permissions for certain keys are not set correctly, it causes the control to fail to initialize. The "Everyone" group has been removed from having READ permissions on certain registry keys due to the mistaken notion that Everyone means ANYONE, when in actuality it simply means all validated users on the Domain/machine. In the case of a file database, such as Access or FoxPro, the directory containing the database files does not provide sufficient permissions for the authenticated user.

您好！ 1、我查了下其他电脑上HKEY_CLASSES_ROOT的权限和我电脑上的一样； 2、为什么要注册msbn3.dll呢？我电脑没有注册也可以创建组建呀？

您好！
我程序里是想调用封装了xml的动态库来创建xml文件，对应的clsid在我电脑的注册表可以找到，如下图：

但是其他电脑就没有注册XML DOM Document 4.0，我想问题就出在这里吧？怎么注册呢？求解答……

不太懂怎么注册哦，求指导

开始菜单-运行 输入 regsvr32 “DLL或ocx全路径名称” 注意路径名称加上引号，否则，路径有空格的时候会有问题

我把动态库放到了c:/WINDOWS/system32目录下，输入指令后提示已加载，但是找不到DLLRegisterServer入口点
