Remember, the key you have purchased is a prepaid code that is not compatible with the pre-installed software. This is an original Microsoft product. Uninstall the previous version of Office that you have on your PC and restart your computer. This is important to avoid compatibility problems.
Microsoft has gradually phased out support for some older products. Therefore, telephone activation is no longer possible. If you have any problems or questions during the Installation, please contact our 24/7 customer service.
