Step 1th, open the Word2013 document window, and click the file → options button.
Step 2nd, open the Word Options dialog box and switch to the Add-ins tab. In the Add-ins list, locate the add-in that you want to enable or disable, and record the type of the add-in (for example, the type "Microsoft Word for Document Wizard Add-in" is a "com add-in"), and then click the Manage Drop-down triangle button.
Step 3rd, select the appropriate add-in type (for example, select COM add-in) in the Manage Drop-down list, and click the Go button.
Step 4th, open the COM Add-Ins dialog box, select or cancel the add-in check box that you want to enable or disable in the Available Add-ins list, and click OK.
The Office add-in that is selected in the COM Add-Ins dialog box is displayed in the Add-ins list in the Word Options dialog box, enabling the add-in. The unselected office add-in is not displayed in the Add-ins list, which disables the add-in.
