Office 365 requires a minimum version of Office to be installed on your computer in order to activate properly. If you have an older version of Office, it will not be able to activate Office 365.

To resolve this issue, you will need to update your Office version to the minimum required version. You can do this by checking for updates in your Office application or by downloading the latest version from the Office website. Once you have updated your Office version, you should be able to successfully activate Office 365.

It is important to keep your Office version up to date to ensure compatibility with Office 365 and to have access to the latest features and security updates. Make sure to regularly check for updates and install them to avoid any activation issues in the future.

Multiple Installations

If you are unable to activate your Office 365 subscription, one possible reason could be that you have already installed Office on multiple devices. Each Office 365 subscription allows you to install Office on a certain number of devices, depending on your subscription plan. If you exceed this limit, you will not be able to activate Office on additional devices.

To resolve this issue, you can try deactivating Office on one of the previously activated devices. Follow these steps to deactivate Office:

Open any Office application, such as Word or Excel.
Go to the “Account” tab and click on “Manage Account”.
Sign in with your Office 365 account credentials.
