Question

我试图在Windows 8机器上运行我的程序，并且它在运行时给出了这个错误（0x80040154（REGDB_E_CLASSNOTREG））。当我在安装了Windows 7的计算机上运行它时，我没有遇到任何问题。

以下是详细信息（内部异常）：

感谢您的帮助。

错误和调用堆栈表示您的PayrollSystem.frmMain依赖的OLE或ActiveX控件，但未安装。至于它想要实例化的组件，还不足以继续。

从callstack判断，唯一可以知道的方法是实际查看frmMain.InitializeComponent中的代码和/或查看表单的资源文件，看看你在那里嵌入了什么。
