Wondering how to get started with your new Office product? Well, that's simple. Just visit office.com/setup from any web browser on your device and sign in using your Office account. If you don't have an Office account yet, you can create one from account.microsoft.com. After signing into your Office account on office.com/setup , the next step is to enter the product key. You can find this key either on the back of the retail card you purchased offline or in one of the emails you received after completing the purchase of your Office product. After the Setup file is downloaded, click on Run / Setup / Save to install the file. Follow the steps on your screen to finish the installation. For more help, visit our Office.com/setup Help portal.
