Shishusingh，

Hi shishusingh,

感谢您的信息.

>>>>>未注册的类(HRESULT的异常:0x80040154(REGDB_E_CLASSNOTREG)."

>>"Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))."

根据您的描述，您正在使用COM组件，并且在使用COM组件之前未对其进行注册.

Based on your description, you were using a COM component and the COM component is not registered before you were using it.

Windows提供了RegSvr32.exe，可以注册COM组件. RegSvr32.exe具有以下命令行选项:

Windows provides RegSvr32.exe which could register COM component. RegSvr32.exe has the following command-line options:

Regsvr32 [/u] [/n] [/i[:cmdline]] <dllname>

/u - Unregister server 
/i - Call DllInstall passing it an optional [cmdline]; when it is used with /u, it calls dll uninstall 
/n - do not call DllRegisterServer; this option must be used with /i 
/s – Silent; display no message boxes

请在使用前注册您的COM组件.有关更多信息，请参见下面的链接.

Please register your COM component before using it. For more information, link below is for your reference.
