Several Updates Not Downloading

[A.N.Jensen]

I imported the latest PMPC catalog, ran a software update sync in SCCM (v1610), but some of the newer updates are failing to download with this error: "Error: Failed to download content id 16915357. Error: There was an error downloading the software update. (404)"

Audacity 2.1.2
Chrome 56.0.2924.76
Firefox 51.0.1 -
iTunes 12.5.5.5
VLC Player 2.2.2
VLC Player 2.2.4

Earlier updates for Chrome (55.0.2883.87), Firefox (51.0), and iTunes (12.5.4.42) are all downloading as expected.

Can you email us the patchdownloader.log from the machine you are trying to download the update from in the SCCM console?
