Remove all data licenses from KeyChain Access

KeyChain Access stores all passwords, including software licenses. If KeyChain Access already contains an entry named “Office”, you are likely to get this error message when activating a new Microsoft Office installation. Therefore, you need to remove all Microsoft Office entries from KeyChain Access. To do this, press Cmd+Space to open a Spotlight search and search for “Keychain Access”. After typing, you need to open the corresponding result.

Now look for “office” in this search box. If you get an item associated with that search term, you need to right-click on it and use the delete option.

Deleting items from the library folder

The library folder on a Mac is a bit like application files on Windows. If you delete certain files, the license will be deleted and you can get an activation window.

Once you have a list of folders, press the Option key. The Library folder should now appear in the menu.

In the Library folder, you should open the Group Containers folder. Here you should see four entries with the names
