Hello Colin,
The reason for the failure to package could have been because Adobe released new updates for Flash Player which replaced the download links for version 18.0.0.160.
We published the following new updates today:
Adobe Flash Player 18.0.0.194 Plugin
Adobe Flash Player 18.0.0.194 ActiveX
Adobe Flash Player 13.0.0.296 ActiveX
Adobe Flash Player 13.0.0.296 Plugin
The following updates have also been updated to point to active download links(archive zip) to successfully package:
Adobe Flash Player 13.0.0.292 Plugin
Adobe Flash Player 13.0.0.292 ActiveX
Adobe Flash Player 18.0.0.160 ActiveX
Adobe Flash Player 18.0.0.160 Plugin
You can wait for the next content download cycle to finish and then attempt to accept the patches.
Regards,
Mansur
