Hi, Theodore Cheek

Since Word is already activated, the license is probably valid. Excel may have damaged activation files, be signed in with a different account, or conflict with another Office installation.

Here are some suggestions you can try:

Open Word and select File > Account. Note the email address shown there. Open Excel, sign out of any accounts listed under File > Account, close Excel, then reopen it and sign in with the same licensed account used in Word. Unlicensed Product and activation errors in Office

Update Office from Word by selecting File > Account > Update Options > Update Now.

Repair Office. Right-click Start, select Installed apps, find Microsoft 365 or Office, select the three dots, then choose Modify > Online Repair > Repair. Restart Windows afterward. This repairs the full Office installation, including Excel. Repair an Office application

If Excel still will not activate, run the Microsoft 365 Activation Troubleshooter through the Windows Get Help app. It is available on Windows 10 and later. Microsoft 365 troubleshooters

If the problem remains, please share the exact error message or code shown in Excel.

Thank you for your patience in reading, I hope this information has been helpful to you.

Thanks for your assistance. Sadly, I purchased Microsoft office 365 but I have learned it does not work (support) with MAC system Monterey 12.7.6, This would require me upgrading my MAC system which would cause a loss of some important old applications. The only way I can use a spreadsheet is to use the MAC numbers application which is not as useful as EXCEL. Ted Cheek

Hi, Theodore Cheek

You do not necessarily need to upgrade your Mac. macOS Monterey 12.7.6 cannot run the latest Microsoft 365 release, but Office version 16.88 was the final build designed to support Monterey. It will not receive newer feature or security updates. Upgrade macOS to continue receiving Microsoft 365 and Office for Mac updates

Remove the newer, incompatible Office installation from the Applications folder.

Download the Office 16.88 suite installer from the Update history for Office for Mac page. Make sure you choose the full Office suite installer, not an individual update package.

Install it, open Excel, and sign in with the Microsoft account used to purchase Microsoft 365. Version 16.88 is above the minimum app version 16.83 required for Microsoft 365 licensing on macOS 12.

Avoid updating Office beyond that compatible version.

If desktop Excel still cannot activate, Excel for the web is included with Microsoft 365 and can be used through a supported browser without changing macOS.

Before removing anything, back up important files and older applications with Time Machine.

Hi, @Theodore Cheek

To help narrow down the issue:

What is the exact error message or error code you get when trying to activate Excel?
What Microsoft 365 or Office license is shown under https://account.microsoft.com/services?

Thanks!
