MobiOffice is no longer supported on Windows 7, Windows 8 or Windows 8.1 now that these operating systems have reached their end of support dates. To avoid performance and reliability issues, we recommend that you move to a newer version of Windows.
Devices running either version of Windows no longer receive security updates. Therefore, if you're using MobiOffice on a computer running Windows 7 or Windows 8.1 and are configured for automatic updates, you'll no longer receive updates for the MobiOffice apps, including feature, security, and other quality updates.
