Hi Rachel B
Thank you for reaching out to Microsoft Q&A Forum and sharing your experience. I am sorry to hear you are having trouble opening Word immediately after installation.
To better understand, please provide following details:
- What version of macOS and Office are you currently running?
- Do Excel or PowerPoint open successfully, or do they crash as well?
- Did you install via the Microsoft 365 portal link or the Mac App Store?
- Please provide a screenshot of the full error message if possible.
Because this is a public forum, I suggest sending any supporting documents or screenshots of the error via Private Message to protect your personal data.
Meanwhile, please try the following steps:
First, make sure macOS and Office for Mac are fully updated.
I recommend performing a Safe Mode system cycle. Shut down your Mac completely, then turn it on while pressing and holding the Shift key until the login window appears. Log in, wait briefly, then restart your Mac normally and test Word.
Word can occasionally run under Rosetta 2 mode instead of native Apple Silicon if the app was migrated from an older device or installed using certain methods. To verify this: Open Finder > navigate to the Applications folder > right‑click Microsoft Word > select Get Info > look for the option titled Open using Rosetta. If it is checked, uncheck it, then quit and restart Word.
If the issue continues after basic troubleshooting, you can follow Microsoft’s official guidance for removing old or corrupted Office license files on macOS: How to remove Office license files on a Mac - Microsoft Support
