C# 无法强制转换类型为'；系统。共对象'；至接口类型'；Microsoft.Office.Core.IRibbonUI'；

嗨，我是新来的excel addin。我已经安装了MicrosoftOffice2010，我的加载项过去工作得很好。为了在2013年进行验证，我安装了2013，并运行了2010版和2013版。最近我安装了2013，现在如果我打开2010版本，我的加载项会加载，但会出现以下错误。请帮忙

错误

An exception was thrown with the folowing information: System.Runtime.CallbackException: A user callback threw an exception.  Check the exception stack and inner exception to determine the callback that failed. ---> System.InvalidCastException: Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.Office.Core.IRibbonUI'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000C03A7-0000-0000-C000-000000000046}' failed due to the following error: Library not registered.

这是一个安装问题，请重新运行Office安装程序以修复注册表损坏。我尝试重新安装Office，但没有任何更改仍然收到相同的错误搜索异常消息时，第一次在Google上点击的是，接受的答案是否解决了您的问题？@Dirk Vollmar，接受的答案无法解决我的问题。我完成了回答中提到的所有步骤。但是没有任何帮助，所以这就是我发布问题的原因。
