I have the same problem, and the other solutions listed don't apply or don't work. Update through Photoshop or Bridge gives the same update server error.

I am running Window 8 pro (update but as a semi-clean install) and have uninstalled Photoshop CS6, reinstalled using the administrator settings (right click to install as administrator). I have installed the the 13.0.1.1 update like this too. Possible factors for me could be:

1. using a different adobe id between lightroom install and photoshop install, and those id's being associated with different countries, and now being in a third country . (Adobe, you make buying your software a NIGHTMARE in a multi-country scenario). Update - although I have been using these two id's for years, Adobe just sent an email to confirm my "recently created" Adobe ID - wierd.

2. Having Windows 7 on another hard drive on the system. Note that for the install of Windows 8 Pro I installed with only one hard drive connected, then later connected my three other internal hard drives. I don't get a dual boot option; I have to change the bios boot order to run Win 7.

3. Another possible factor is my first download of CS6 was corrupted, a couple of times, and only after downloading the whole thing again was I able to install properly.

BTW, how do we know if the update has arrived when we can't even update in tyhe first place?

haha ok, thanks again!

PROBLEM RESOLVED!!! I FINALLY FOUND THE SOLUTION!!!

~For Windows 8~

1) Under Control Panel, navigate to the top right search bar and type in "device manager"

2) Click on "Device manager" after the search

You should see a tree-like map of your devices in the new window

3) Navigate: view>show hidden devices

4) Under "Network adapters", right click on the "Microsoft Wi-fi Direct Virtual Adapter" and select disable.

5) Run updates for your Adobe software on your Windows 8 machine and VOILA!!

Glad I could help!

However about your question and concern... I'm not very sure about it.

Actually if you look at many other discussions about this "update server not responding" issue, the main solution would be here: http://helpx.adobe.com/creative-suite/kb/error-update-server-repsondin g-cs4.html

However, this solution seems to ONLY work for windows 7, and  in Windows 8, I don't think you can locate the "Microsoft Virtual WiFi Miniport Adapter" under the "Network and Sharing Center" like in Windows 7.

Hence, I accidentally stumbled upon the solution for Windows 8 while playing with some of my computer settings and saw the "Microsoft Virtual WiFi Miniport Adapter" under "Device manager".

I couldn't locate the Microsoft Virtual Adapter in my Network and Sharing or in Device Manager to disable. So I searched the web and found the following link that resolved the issue of locating it:

Once I followed the enabling instructions I then went back to Network and Sharing where I was then able to disable the adapter.  And like magic I was able to receive CS6 updates.
