Foxit Software installed some time ago, whether it is the result of wps office or in the menu bar are extra-sensitive menu of Foxit, unsightly and impractical. Mother of the one hundred days but could not find, that is set up inside the menu. (People's logical thinking is the way things appear in any place will think from where to start)

And finally found com add-in problems.

Understand, Foxit software is installed at the same time also installed office and wps plug on Foxit, com add-ins is to Foxit this plug-in software to be loaded into the menu. So we let him set can be loaded in the software.

wps can operate directly in the File menu com add-in tools, office is required to operate in the add-in options.
