SharePoint 2013 "Help Menu" not working (Sorry, the page you're looking for can't be found)

Question

The Built in SharePoint 2013 Help Menu (?) on our Enterprise Farm for both the sites and Central
Admin does not work.
On Central Admin help the error comes back as: "Sorry, the page you're looking for can't be found".
The site collections Help menu gets the error :
"Unfortunately, help seems to be broken...
There aren't any help collections in the current language for the site you're using."
We have installed on all servers in the farm:
December 9, 2014 Cumulative Update for SharePoint Server 2013 package (build 15.0.4675.1000)
as well as the latest SharePoint update KB2768001 1/15/2013.
I have checked:

The URL for the site collections is https://servername...../_layouts/15/help.aspx?Lcid=1033&Key=HelpHome&ShowNav=true
We are only using Default English (US) language packs.
In the directory of
Directory of C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\HCCab\1033
there are cab files.
There are no pending upgrades on any SharePoint or SQL server, all other SharePoint components are working
normally.
Any ideas or suggestions?
Thanks.

Answer 1

I'm interested in getting the local help to work while this is offline, I saw the following in an article, did you do this and it still does not work for you?
"However the help won’t show up in
SharePoint 2013 sites. You need to change the Help Collection item property SharePoint
Version to15 to
make it work."
