The 64-bit version 5 of LibreOffice:https://www.libreoffice.org/download/li ... lang=en-US
If you like it send the $50 you would have spent on the crippled Corel Office as a donation to LibreOffice to support their work, cuz developer's spouses like to eat too.
Why do I say crippled? Because I use WordPerfect Office (but I only install WP) which is the best IMHO for writing. Corel Office reminds me of MS Works. A substandard office package.
I won't say LibreOffice is perfect but it is amazingly good for free. Is kept up to date. Comes in 64-bit. And runs on Windows, Apple or Linux OS. Database app needs some serious improvement though.
