"axesPDF for Word" tab disappeared

A. Your situation

Word is crashed. After re-starting you get the a message similar to the following:

"Word experienced a serious problem with the ‘axespdfforword’ add-in. This add-in is incompatible with Data Execution Prevention mode and should be disabled or upgraded to the latest version. Do you wish to disable this add-in from loading?"


Read the message carefully!

Clicking "No"?

If you click "no", then the axesPDF tab still appears in the ribbon. You can use the add-in as before.

Clicking "Yes"?

If you click "yes", then the axesPDF tab disappears because Word disables the add-in. The following tutorial guides you through the workflow to get your axesPDF tab back:

    A more serious issue is when the AddIn does not appear in the list despite being installed.
