Photoshop not installing, says there's not enough space on drive with 549gb

[LikelyPrettyConfused]

I set the Creative Cloud to install things to my D drive, which has much more space than my C drive, but when I click "Install" on Photoshop, it gets around 27% in and then stops and says there's not enough space, even though there's 549 gigabytes free in the drive. It makes a folder in the D drive, then doesn't install anything into it. Did I do something wrong? Is it a bug? I need help.

No.  You need ample primary hard disk space to install Creative Cloud desktop apps, even if you install to a different drive.   See the system requirements.

Hard disk space

3.1 GB or more of available hard-disk space for 64-bit installation; additional free space required during installation (cannot install on a volume that uses a case-sensitive file system)

So I need my C: drive to have 3.1gb free to install it on a different drive? Because my C: drive physically can't have more than 111mb on it.

Sounds like that may be the problem. It needs a little "wiggle room" on your main drive to get things set up properly. 111Mb is pretty small.

Why has it sinatlled OK and updated OK with that much space until suddenly now, it desides it cannot?
This is weird

I have 3.79GB free on C drive but 'insufficient'? Weird!

That's not enough to run the system. Systems sold with tiny C drives were obviously not intended for serious computing. A system without tens of GB free is in a critical state, even without CC

Get a new computer. 

Your operating system alone without any other apps or utilities consumes HD space and RAM.  Windows 10 (64-bit) takes up 20 GB of HD and 2 GB of RAM.   Allow additional resources for peripherals including graphics display, mouse, printers, scanners and external drives.  Then add more resources for all other apps & utilities + Creative Cloud + Photoshop + Photoshop's scratch disk. 

As an example, my aging workstation has 1TB hard drive and 32 GB of RAM.  I also have a 1.5 TB external drive.  My Photoshop Scratch Disk has 1410 GB of free space available.  Even with that, I still can't use the latest version of Photoshop because my GPU isn't sufficient.

Before you rush out to buy a new PC, do some research.  Make sure it meets or exceeds the minimum requirements to run Creative Cloud + everything else you use.  Buy the best machine you can afford.
