Office Web Component (OWC) is missing in Office 2007

Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG), have you ever come across this error information? I uninstalled all my office components yesterday, and reinstall the official version of Office2007. So, this message appears while trying to browse a cube in the SSAS. The reason is that this operation depends upon OWC, which had been shipped together with the previous Office products, but is now dropped in Office 2007.

Some other guys also claimed this problem, and a solution is proposed. Reinstall OWC can resolve this. Also, another Chinese developer wrote a good article on his blog about this in Chinese.

The OWC download site.

在重装了Office2007之后，我在使用SSAS浏览Cube时，遇到了这个错误：Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)。原因是这个操作使用了一个叫做OWC的组件，这个组件是随着先前版本的Office自动提供的，而在Office2007中却没有它。还有人也遇到了同样的问题，解决方法就是重新安装一下OWC。这里还有一个中国的开发人员写的blog，很好地描述了问题所在、解决方法以及一些基础知识。
