What is this "Update Available" popup?
Normally the RevelDigital player software will download and install it's updates in the background without any user intervention. This popup will appear in situations where an update was started but was interrupted or timed out during the download. This may happen if a network cable is disconnected, a wireless router is turned off, the player is rebooted, your network is experiencing heavy traffic, etc. A failed download requires manual installation of the update which is the reason for the popup. The player software is roughly 35 megabytes in size so depending on your network speed the update process could take a few minutes.
If the popup appears just connect a USB keyboard and/or mouse and click 'Ok' to restart the update process. Once installed it will resume the normal background update procedure.
