Error installing CS5 updates; Some updates not showing up.

Question

When I select a photo in lightroom 5 and opt to edit it in photoshop, I get a notification that says "This version of Lightroom may require the Photoshop Camera Raw plug-in version 8.3 for full compatibility. Pleas update the Camera Raw plug-in using the update tool available in the Photoshop help menu."
Upon entering photoshop and opening the update tool, there are two updates, but neither for the Camera Raw plug-in. I went ahead and tried to update those anyway, and at the end, I got two error messages reading "There was an error downloading this update. Please quit and try again later." and "Installation failed." The updates were for Adobe Extension Manager CS5 5.0 and Adobe Device Central CS5.0.1, respectively.
My question has two parts. First, how can I work around these error messages and successfully install the updates, and second, why is the Camera Raw plug-in update not showing up? Thanks in advance!
Below are screenshots of the Lightroom message and the update error messages.

Answer 1

What updates should have been available, and
Why were they not available at that time?
Lets examine the case of the backup that has been on the shelf a while.
I really would like to help, but this post does not really answer my two questions. If you want to troubleshoot this scenario, we're going to need some HARD information to work with.
WSUS reported (updates needed report) that there were 90+ updates available and approved for that machine
The computer reporded that there were no updates available.
My first eyebrow-raising moment here is the idea that a computer has 90+ updates
approved and available (and, ostensibly, cannot find any of them to be downloaded), and my very first question in response to raising that eyebrow is this: And all 90+ of those updates are NOT SUPERSEDED??? To which my second question would be: When
was the last time that machine had patches installed?
I took a look at another computer in the same OU and computer update group with the same initial install image and I see 12 updates available, all not yet approved for that group.
If the updates are Not Approved, then those updates are also Not Available.
I'll also point out here that the best way to approach this scenario is to believe what you see and investigate the reason why, rather than questioning the veracity of what's displayed in the console or the logs.
If the client says there are no updates available for installation, then that's the bottom line, and the proper response is to identify an update that
should be available for installation and determine why it's not being downloaded/installed.
