Word might require you to allow some actions before it initialises Chronolator. In particular:

• you might need to Enable Editing if the document opens in Protected View
• you might need to Enable macros, depending on your macro security settings

You will also need to accept the terms of the Chronolator licence if you have not already done so since you opened Word.

For details, please refer to the following:

• Protected View
