Someone sent you a .docx or .pptx format files and you are wondering what on the Earth they are and how to view them?
Well it is simple it is another stupidity from Microsoft forcing you to buy new software or become extinct.
To view/work them and Microsoft compatibility pack which can be downloaded from following links. Bookmark this page for easy access otherwise you will end up spending you whole life searching for it.
I’m trying to install this compatibility pack and I get error “Installation Failed”. Any solution?
