My licensed copy of CS6 downloads but won't accept the serial number

Question

I have a licensed copy of Photoshop CS6 (supplied only as a download by Adobe).  Following a computer crash, I needed to re-install CS6, the download completed, the software then asked for the serial no. which I duly entered, and despite the fact it is the registered number for this software (also shown in our Adobe account and from my own records), adobe will not register it, instead a window pops up after entering the required details, claiming that the registered number is not for the product it just downloaded.  This is a total contradiction of what is clearly shown on their own log of my purchases, which show exactly the same number entered for my copy of CS6.  Of course, despite the fact I only bought the damn software 9  months ago, they do not allow access to support in order for them to correct something that is clearly Adobe's own bug.  Basically, I have bought a very expensive program and they, in their wisdom have created a problem that means I can no longer have access to it.  This is daylight robbery and a shameful way to treat loyal customers who have spent thousands of pounds over the years for licensed copies of Adobe software.  All I ask is that a customer service advisor, correct the fault and register my copy with the number it has on record, because, for some reason, it won't let me do it.  I have today worked with a kind Microsoft technician for 6 hours, trying to re-install my licensed copy on to my restored version of windows to no avail, Adobe really do need to give people access to their own staff so that registry errors like this can be solved.  Lets face it, a forum is not going to be able to fix this one is it.

Answer 1

I downloaded the trial version of Photoshop CS6 (standard) from Adobe, once finished it then opened a window asking if I want it activated as a 30 day trial or as a licensed copy and once I choose the latter. It requested the serial number, so I entered the serial number applying to the licensed version I have of Photoshop CS6 (the same program I downloaded) which was then rejected, with an error message that stated that, although the serial number is valid, the program cannot be found on my computer (that is a mystery to me, given that it has just spent half an hour downloading it and has followed the download with the prompts), I was then prompted to choose from a drop down menu below.  The drop down menu shows the extended version of Photoshop CS6 but not the standard version that I bought last May, effectively preventing me from installing my own version of the software.  Is this a way that Adobe have of forcing everyone into ongoing contracts on cloud.  I just bought the program, I don't want to go on cloud.  Adobe's security was breached before and why should I be forced to pay twice.
After helping me reinstall windows 8.1 on to my computer an Engineer from Microsoft struggled with this all afternoon and most of this evening, and even he could not get it to work, so what chance have I got if he can't do it and Adobe refuse to help.
