I installed MathType 6.9 when I edited the formula under Office 2010. Initially available, but there was a problem installing MathType from another source.The word times are wrong to open.
The search on the internet said that the previous uninstallation was not completely caused. If you no longer use MathType, you can add%program files%\microsoft office\office14\startup\ path Mathpage.wll and MathType Commands 6 for Word 2010.dotm files can be deleted.
If MathType is required, copy the file%program files%\mathtype\mathpage\32\mathpage.wll to%program Files%\Microsoft office\office14\ Startup\ the path. This is for 32-bit Office 2010, 64-bit needs to copy%program Files%\mathtype\mathpage\64\mathpage.wll to%program Files%\Microsoft office\ Office14\ path instead of startup. There is no distinction between many of the introductions on the web here, which I found when I used 32-bit and 64-bit office. Office14 in the Microsoft Office installation directory represents Office 2010, and Office15 represents Office 2013, so office 2013 needs to be modified under OFFICE15.
