可能是由 一些注册表错误，可以通过运行注册表清理软件或输入以下命令来修复:

It can be caused either by some registry errors which can be fixed by running a registry clean up software or entering the following commands:

regsvr32 atl.dll
cd C:\WINDOWS\eHome
ehSched /unregServer
ehSched /service
ehRecvr /unregServer
ehRecvr /service
ehRec.exe /unregServer
ehRec.exe /regserver
ehmsas.exe /unregServer
ehmsas.exe /regserver

或者由不匹配的 .Net 框架版本引起(有时客户端版本没有工作，您必须安装完整版)或其他先决条件.尝试重新安装 .Net 框架.

Or caused by a mismatched version of .Net framework (sometimes client version doesn't work and you have to install the full version) or other prerequisites. Try re-installing .Net framework.

如果此后问题仍然存在，则可能是操作系统出了问题.

If the problem lingers after that, it might be something wrong with OS.
