You have to have Windows 7 Professional, Enterprise, or Ultimate.
I think you need Windows 10 Pro edition if you go Windows 10.

Firstly Dangz I have to ask...
and I'm surprised no one has yet...
are you using win7 Home Premium?
There are other constraints that could be effecting your overall total RAM availability.
Sure Home Premium is the obvious first go to choice. But there are limiting factors in certain older hardware as well. Motherboard as well as CPU can be a factor.
Judging you're using ddr4 that shouldn't be the heart of the issue but it's good to be clear the OP is not mistakenly posting wrong hardware specs accidentally...
anyways... So I asked the easiest question in the world... so time to follow it up with the next can you list your system specs for us Dangz.
I would like to say that if you have a valid activated copy of win7 you will be able to upgrade to win10 for free... but you should know this already seeing that weird little windows icon thing down in the taskbar by the system tray.
If you need to buy a version of windows then I would say any system utilizing ddr4 should be ready for win10... but again I shouldn't automatically jump to conclusions here either.
I think you've been given some good advice thus far overall by everyone Dangz but if you don't mind giving us a few more details we can be sure that it's the best advice without a doubt.
I jumped into this one late in the game...but I just had to ask.
You've probably moved on to bigger and better problems by now
and if you got this one handled already then let us know how it went Dangz.

Well thank you for the info Dangz.
Being we know you should as Microsoft points out in their own specs be theoretically able to address up to 192GB using win7 pro x64 the issue has to be further down the line.
Firstly I would look up your motherboard and CPU specification for maximum physical address of RAM that each is capable of supporting.
This information is easy to find even if you don't know a thing about your PC or how to open the case.
A simple free program like cpuZ will list all the critical information needed.
With this information in hand you can look up the specifications for the motherboard and the CPU and find out if the maximum supported RAM for each is able to be greater than 32GB. Sure the OS has something to do with it but not all... I can assure you not many consumer grade PC's are able to address anywhere near the 192GB limit due to physical hardware constraints that intel or AMD has placed wtihin the processor or likewise a limitation that is found within the motherboard itself.
You may already know all this... but I don't know that you do.
The information you will want to look at immediately would be the PROCESSOR NAME in the initial CPU info, the MOTHERBOARD MODEL nomenclature under the mainboard headings as well as the BIOS VERSION and DATE also under the MAINBOARD tab.
It probably also wouldn't hurt to look at the MEMORY tab and see how much physical RAM is being reported as well as checking each individual available RAM slot individually to see what is listed under the SPD tab.
If it appears to list your physical 64GB RAM here as well as posting the appropriate readings for voltage timings etc for all RAM modules under each individual RAM slot then more then likely your issue is at the maximum addressable value that the motherboard or the CPU can handle. If either of these has a physical limit of 32GB then that is where the issue is going to be. I don't think that you have bad RAM modules installed as the PC probably would have some problems posting or at least hanging when loading at post initially. The fact your computer apparently is functioning in windows without issue says to me that it is able to handle and see the RAM but isn't able to utilize it completely for whatever reason.
With the info in hand proceed to your motherboard manufacturers website and check the specs. It should list maximum supported RAM for the model. It also wouldn't hurt to look up the most recent bios update for your motherboard while you are at your motherboard manufacturers website and to look and make sure you have the latest bios version installed as this may be causing the issue as well. All manufacturers will continually update their bios for further compatibility when known issues are found and fixed and provide these revised updates usually until it doesn't become feasible for them to put any further effort into the product usually due to it being outdated. Most provide an easy to update within windows download for the process... though not all.
Also be sure to proceed to Intel or AMD's website and verify the processor can support more than 32GB as well.
Some hardware doesn't play nice with each other and there just could be an issue with the RAM modules your running and your motherboard model. Many manufacturers have an approved list of tested supported compatible products and sometimes you just may have gotten that one specific combination that isn't agreeable. This is especially true when running higher amounts of RAM then what the majority of users are typically installing. Though I would think this would be the last place to look if all else still is not proving to be the issue.
At the least you can take all that information you gather as well as maybe the RAM manufacturer and model number and any other pertinent information about your system... more is usually better than less... list it all here in some random yet hopefully intelligible manner so someone will be able to use it to give you a better answer then I am able to thus far stabbing in the dark.
I sincerely hope you can resolve your issue... or at the least find out definitively why you can't.

*Slaps 4head*
Disregard last reply Dangz, doesn't apply anymore.
I could totally rewrite the whole previous post but would rather it live on as it may help someone else get their own problem worked out.
Sorry didn't reread the original posting.
It's been a while.
16 of 32GB not 32 of 64GB.
For some reason the last thing you replied left me with the impression you still hadn't fixed this thing and I remembered it was double what you posted.
I blame this on the Holi-daze I have been under recently.
Anyways it looks like you fixed this thing I guess Dangz.
To answer the last question you will always have a little bit of your physical amount be inaccessible due to the OS setting it aside for system resources. This is usually for hardware required cache for PCI devices such as onboard Sound or Video controllers but can be for just about anything. Usually not more than 256MB and mostly lower then 100MB but this can vary.
So 31.9 of 32GB is normal.
