Cannot Install Photoshop CC Due to "Insufficient Disk Space" Despite Changing Directory

[adamw13404180]

I've been unable to install Photoshop as I constantly get this error whenever I try, despite my changing the installation directory to a drive with 133GB of free space. Does anyone know how to fix this?

What is your OS and version and how much space is on your system disk?

[adamw13404180]

I use Windows 10 and I have 2GB free on the system disk.

Not enough space

1 - some parts of the Cloud manager will ONLY install on the boot drive

2 - not sure of this, but I think temporary files also go on the boot drive

Install on non-boot drive see reply #1 https://forums.adobe.com/thread/2549431 may have more information

How much space do I need? As there is pretty much nothing I can remove from my root drive?

It sounds like you need a bigger computer.

2GB on the system disk is even not enough to run the OS. Even if you instal on a different disk, the OS needs some space on it’s own to organize the stuff you’re doing. You should urgently free-up space or get a higher capacity system disk.

A little bit OT, but I can remember that my first harddisk had just 5Mb!

And I remember creating a stripe of 4 500Mb disks on our mini super computer (with an overall power of less than what I use now as a phone) just to crash the OS, because the Unix system used signed integer as a disk location pointer and on a 32bits system you can represent a positive number up to 2Gb-1.

And now you fail your install because you “only” have 2Gb free. I would love my salary being so inflationary... .

Sorry about that as it does not solve your problem but sometimes I remember things from the dark ages of computing...

2GB FREE on the system drive is plenty.  Except when a stupid installer like photoshop insists on using C: for something when I am telling it to install on a drive that has 250GB free.  Adobe should fix the installer.

See Photoshop system requirements  Even if you try to install on a 2nd drive, your primary hard disk must have sufficient resources to install software.  This might be a good time to move data and work files to an external drive and uninstall all non-essential software to free up space on the primary disk.

The requirements you link to above only say how much free disk space is required.  It doesn't say that the free space MUST be on the boot drive!  On top of that, the error message you get when install fails is wrong as it says "...only '1278648320' bytes are available on the installation directory"  when the installation directory (drive) has 250GB free.
