Please uninstall and re-install this product Error Code 6

Question

I have 7 users running single licenses of Adobe Acrobat X Standard and 5 users running a multi license version of Adobe Acrobat X Pro. between Wed 14/01/15 and Thursday 15/01/15 all of these products stopped working on all machines. All machines are windows 7 machines. They are throwing up
"Configuration Error"
Please uninstall and re-install this product.
Error code 6.
It then closes the program
When i run this product as an administrator the error message still appears but it allows the program to run. When i then close the program it does not close to process so the next time i open adobe it gives me the error message that the product is not licensed. I assume this is due to the product running in 2 instances.
I have tried:
un-installing the product,
i have currently set all my users to local admins to have a work around.
I have used the adobe clean up tool and removed everything i can think of to do with adobe.
I have re-registered the products
I have edited to permission and followed the guide for Error Code 16 as it was a similar problem.
None of the above has worked so far.
This is now a matter of urgency and any help would be appreciated.

Let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you? If so, does iTunes launch properly now?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)
