Why am I being told that I must upgrade my VZAppZone client application?
When an upgrade for the VZAppZone client application is available, you will receive a notification indicating that a new version is available. Once you receive this notification, you may choose to install the upgrade immediately, or (if you wish) you may choose to wait until a time that is more convenient for you. However, if you choose to install the VZAppZone client application at a later time, you will be unable to use the client until you perform this upgrade. This is because there may have been critical changes made to the application that will potentially affect its performance.
