microsoft Word not saving documents

Since you can open up new Word files that says you don't have a 32 bit Word app.To start, there are a couple of things to try. I would restart your Mac in the safe mode. As it is starting up. hold down the shift key. Start up can take up to 10 minutes as the os is doing fixing, cleaning and maintenance. Then I would run the Disk Utility app until it says no problems found. Next, restart as usual and see if anything is different. You might also then reload the Word app in case it's corrupted. If this all fails, I would recommend reloading Catalina.

Do this by restarting the computer and holding down the Command and R keys at startup.

If that doesn't correct the problem, then I would download the EtreCheckPro free app. It was created by advanced Mac users here. You can then post it here and it can tell precisely what you have installed that might be problematic. Good luck.

Kellie, you haven't given us much information to go on. What version of Word, or Office, are you using? If it is an older 32 bit version, it won't work and that is what's happening. Can you still create a new document? If not, then you will either have to upgrade your version or replace with a 64 bit version. Please also note: if this is the case, none of your other 32 bit apps will work either and they also will have to be upgraded. If this is not the problem, then please provide the following information: your year and model Mac, the os you were upgrading from, and the version of your Word or Office. Then other suggestions can be made for you.
