Repeated attempts failed to update to:
Version 29.0.0.113
Today successfully updated via Avast Software Updater:
Adobe Flash Player ActiveX plugin to Version 29.0.0.140
Adobe Flash Player Plugin update to Version 29.0.0.140.
Hence, multiple attempts failed with the earlier version.
No problems today for same system with a different/later update to these Adobe Products.
Takeaway…issue was not likely due to anything on this end but rather a problem with the Avast updater - at least for this system.
This behavior is consistent with past observations.
