推荐答案

该错误意味着您编写此代码的Excel版本未安装在计算机上。

That error means that the version of Excel you wrote this code against is not installed on the machine.

谢谢Dave ---我查了一下并且确认，我已经从快捷方式发布了。这促使我对安装进行了修复，解决了这个问题。虽然我不确定究竟修复了什么。

感谢大家的回复！

Thanks Dave---I checked, and confirmed, that I have been launching from a shortcut. This prompted me to do a repair on the install which has solved the issue. Although I'm not sure what exactly was repaired.
Thanks for everyone's responses!
