If you have MS Office 2003, you may have been desperate and frustrated when they have passed you a file created in MS Office 2007 (for example, an MS Word DOCX file), as they are incompatible formats. So that this is not a problem, the same Microsoft company has created this MS Office Compatibility Package, also known as "File Format Converters", to avoid these compatibility problems between the different versions of its well-known office suite. Something that you will appreciate all its users who have worked with the affected deliveries, and have several documents that cannot be opened or edited in the most recent ersions.
The MS Office Compatibility Package feature is very clear: install a new pack on your MS Office 2003 so you can read MS Office 2007 files; that is, make them fully compatible. It allows to open files of extension DOCX (of MS Word), XLSX (of MS Excel) and PPTX (of MS PowerPoint).
Of course, MS Office Compatibility Package is perfectly localized to the English language, so it will not be a problem to use it, and in addition, it is a "freeware" application, which means that anyone can download MS Compatibility Package Office free.
You can free download Paquete de Compatibilidad de MS Office and safe install the latest trial or new full version for Windows 10 (x32, 64 bit, 86) from the official site.
