类未注册异常 [英] Class Not registered Exception

问题描述

最近我在xp系统的visual studio 2008中将该项目从vb6迁移到vb.net，并在框架2.0中工作正常。之后，我将框架改为3.5，并在x20中打开了vs2010中的项目，只有这样，我的工作正常。

现在我将我的操作系统更改为Windows 7.这里我打开了项目，我有一些问题我解决了然后构建它成功了。但是当我试图运行我有如下错误

创建表单时出错。有关详细信息，请参阅Exception.InnerException。错误是：类未注册（HRESULT异常：0x80040154（REGDB_E_CLASSNOTREG））

解决方案

这需要更多的细节。请包括内部异常详细信息和调用堆栈 - 这将有助于确定哪个组件抛出错误。

错误本身很清楚 - 您正在使用的类之一没有在Win7系统上注册（即：缺少DLL等）。这可能是因为组件/库从未安装在Win7系统上或安装已损坏。这也可能是因为它是一个32位组件，您在编译选项中定位 AnyCPU 或 x64 。

Recently i migrate the project from vb6 to vb.net with framework 2.0 in visual studio 2008 in xp system it is working fine in that. After that i changed the framework to 3.5 and opened the project in vs2010 in xp only there also it is working fine for me.

Now i changed my Operating system to windows 7. here i opened the project i got some issues i solved and then build it it is succeed. but when i am trying to run i got error like below

An error occurred creating the form. See Exception.InnerException for details. The error is: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

解决方案

This needs more detail. Please include the inner exception details and the call stack - this will help to determine which component is throwing the error.

The error itself is clear - one of the classes you are using is not registered on the Win7 system (ie : missing DLL, etc). This could be because the component/library was never installed on the Win7 system or the installation is corrupt. It could also be because it is a 32-bit component and you are targeting AnyCPU or x64 in your compilation options.
