Same thing happening here.  Every time it launches I get a message telling me there's new content to be downloaded.  When I tell it to update, a window pop up telling me to wait while the downloaded files are extracted.  I've let it sit over night with no changes.  There is no activity on the drive what so ever.  It's just sitting there ...  As corwinsl said, this is broken.

If this is about the previously downloaded files and something getting stuck, then how do we get rid of them and let it start fresh again?  Because obviously letting it just sit here isn't doing anyone any good.  If it's broken, then it needs to be fixed, not ignored.

I was having this exact same problem and was able to fix it.  The problem is due to the update for "ActionScript 3.0 Reference for the Flash Platform".  That one was showing as "Unavailable" under the "Local Content" section.  So I went to the Download Preferences section and unchecked all the options for Flash, Flex, and Flash Builder so it wouldn't try to get that particular update.

Then I went to General Settings and clicked Download and everything started downloading like it was supposed to and all mine that said Pending Integration updated to current.

So yes that did the trick!

Then I went back to the Download Preferences and rechecked the Flash, Flex, and Flash Builder and they started updating as well.  When it got to the ActionScript Reference, it did pop up the "Please wait while the downloaded files are extracted. Extracting large files may take several minutes." message again but this time it really did only take a couple of minutes.

Now I have everything updated.  Hope this helps anyone else.

Pretty much the same here with no error messages.  I can download, and see progress bars for the downloads, network interfaces indicate a download is happening, but as far as things get are "pending integration". The only things that say "Current" appear to be the same ones identified that way at the first invokation of Adobe Help Manager.

I think Adobe needs to provide a tool to allow users to force integration, or, if some temp file has gotten deleted over the months, re-download and re-integrrate the content.

Some of this could be Adobe installer problems.  If I run a registry error scan, I get reference to several Adobe products I have installed, but the installer has misspelled the directory path in the registry entries so they appear to point to non-existent locations.

Also, AE and Illustrator (CS 6) will not let me open any file - earlier generation or current - unless I "Run as Administrator" even though I "own" the files.  Go figure.

Same here. Please wait. Let it run over night.

The InDesign reference now says "Current" but the Photoshop (30 MB) is still "Please wait"

I actually have to agree with Lee here..why cant Adobe provide .pdf help manuals???.. removing and reinstalling the whole master collection is a time consuming task..c'mon Adobe surely you can provide a better solution..as it stands your flagship sottware doesnt have access to help files built into it or you are unable to download the required info for the programs..Lift your game..we pay good money for your products!

Thank You Jeff, we appreciate your help
