Some updates failed to install.

Any Help, please?

Here is a reply I found on another thread. I went to the Manual Products update Product updates and downloaded some so-call updates but I can't open and run 'em. Adobe has proven to be a company that cares little about customers who have spent $,$$$.$$ with them over the last 15 years.  
Another's answer:
I have same problem. After you download updates within the Adobe Application Manager box and get that dreaded Updates failed to install...  look on lower left and click on "Customer Support" link. It will open a new window and tell you the error code.
Do you get Error "This serial number is not for a qualifying product" | CS6, CS5.5, CS5 ?
That's error I get. 2 chat sessions so far, neither person could figure out why, both said to use forums. Two hours later and I find no clear answer.  Best I find googling is CS5-6 is no longer supported. ...meaning if you have less than CS6, you need to manually install updates. The automatic update manager won't update for us any longer, and you need to go here and update all programs manually:  Product updates
