It is not a good idea to install Office executables on your personal computer in any case, because it is a vector for hacks. Many attacks work by getting you to download and open an office document or a PDF file. Office and Acrobat are very old products written in languages without memory safety, which means they are an easy vector. If you need to open Office documents create a OneDrive account and upload the file. Now you can open the file for free, in an browser, without exposing your computer to any attacks.
