What about microsoft office with a 64 bit MacBook Pro operating system?
How do I get my 32 Bit Microsoft Office to work on the 64 Bit Apple upgrade?
MacBook Pro 15″, OS X 10.11
If you won't be upgrading past Mojave, leave it as is. Otherwise, you need to either upgrade to Office 2016 or newer, or switch to a product such as LibreOffice.
