Among the applications we find all kinds of tools for the business environment or for the home. Office is a set of Microsoft applications and products for all kinds of office tasks such as writing documents, creating presentations or creating tables, for example. You probably know very well what it is and have ever used it. Today we explain why it happens, how you can try to solve it or what alternative measures you can use in case you need create a document or data table. A window prevents us from accessing or using all of the software's features because it ensures there are unlicensed product issues or activation errors. One of the most common problems we have when trying to open Word (or Excel or any other in the suite) are activation errors or problems that indicate that the license is invalid or has expired.
