…and our OP still is not giving enough details.We don't even know whether the "client" is running the 32-bit or the 64-bit binary of CC. My guess is that they're running the 32-bit version, so the amount of installed RAM it can access is ridiculously small, as little as a mere 1.7 GB.
This table lists the amount of RAM available to Photoshop with the different versions of Windows:
| Photoshop version | Windows version | Maximum amount of RAM Photoshop can use |
| 32 bit | 32 bit | 1.7 GB |
| 32 bit | 64 bit | 3.2 GB |
| 64 bit | 64 bit | as much RAM as you can fit into your computer |
