Symptoms

When performing a remote Player upgrade from Moxie Studio, one or more Moxie Player upgrades fail with the following error message "Not a valid Omnivex signed upgrade file"

Cause

When a remote Player upgrade is initiated, the upgrade file is sent over to the Player PC and its signature is verified to ensure the file is not corrupted. Sometimes, due to certain security reasons if the Player PC can not verify the file's certificate, it aborts executing the installation file.

Summary

Upgrading to Moxie 7.04 can revert all Log Server configurations to the default state. In addition, it can also cause the Log Server to be listed twice as a connected Moxie application. If this occurs, the Log Server is unable to write logs to the database.

Symptoms 

Before Upgrading

In this example, the Log Server:

For Moxie 7.03 and lower

Note: Moxie 7.03 64-bit does not have video capture

For Moxie 7.03 and lower the tested Video Capture USB devices are:

1. Hauppauge WinTV-HVR-1950
2. Hauppauge WinTV-HVR-1955

PCI versions of these devices are 1600 and 1800.

These devices use MPEG-2, which is not installed by default on Windows 10. However, the codecs are available for installation from Hauppauge.

Symptom

Moxie Player or Studio will restart automatically if certain conditions are encountered such as repeated failures to render video files or when unexpected exceptions are thrown. As part of the Moxie’s process to recover, it will write a timestamped incident log file to C:\ProgramData\Omnivex\System for analysis and then trigger a process restart.

Symptoms

Note: As of July 2021, Microsoft no longer supports SQL CE

Prior to making any changes to a Moxie Data Server host, Omnivex recommends performing a complete backup of your configuration.  If hosting the Moxie Data Server in a virtual environment, a snapshot of the VM is recommended.  Otherwise, backup instructions can be found here.
