How to Add INS in Word 2007

1. Double-click the Word 2007 shortcut icon on your desktop to open the program. Alternately, click the "Start" button and click "Office Word 2007" from the Start Menu's "All Programs" list.
2. Click the Office button. Click "Word Options."
3. Click "Add-ins." Click the name of the add-in you want to enable from the "Inactive Application Add-ins" section to highlight it. Look at the add-in type for the add-in listed in the far right "Type" column (e.g., COM add-in or Smart Tag).
4. Click the "Manage" drop-down menu box located near the bottom of the "Word Options" window. Select the add-in type that is listed for the add-in you want to enable. Click the check-box for the add-in you want to enable so that a check-mark appears. Click "OK." Word 2007 automatically adds the appropriate button or control to the Ribbon, or adds a completely new Ribbon in some cases.
5. Click the "Options" button on the Security Warning message that appears in Word 2007 if the Trust Center does not recognize the third-party add in you attempted to enable. Click "Enable this add-in for this session only" or "Enable all code published by this publisher" to always trust the add-in publisher. Click "OK."
6. Click the Word 2007 Office button. Click "Word Options." Click "Trust Center." Click "Trust Center Settings." Click "Add-ins" in the "Trust Center" window. Click the "Require Application Add-ins to be signed by Trusted Publisher" box to enable or disable this setting, depending on if you want Word, in future instances, to automatically disable add-ins that have not been digitally signed. Click "OK." Click "OK" to close Word Options.
