We are constantly enhancing the product, including improvements in the Activation process. NOTE: If you installed Office Timeline Free Edition earlier and are now activating it after several weeks or months, please make sure you install the latest version before following these steps. Office Timeline has a manual activation process designed for this scenario. In corporate environments, firewalls sometimes restrict this process from taking place. When you enter a product key, Office Timeline activates itself by validating the key with our license server. This article will guide you through activating your new Basic, Pro or Pro+ license.
