Recommendation: For a truly "no need to install" experience that won't crash or infect your host PC, use LibreOffice Portable. It is open-source, free, and designed from the ground up to be portable.
Chinese and Russian forums release "Green" or "Portable" editions that use a batch script (install.cmd) to inject registry keys temporarily. You must run this script as administrator before using Office, and a separate uninstall.cmd script to remove the keys. This is not truly portable—it requires admin rights, which you don't have on public library or university computers.
