I have trouble downloading the game

I get message free up 8 GB of physical system memory. You have available 3.8GB of 8 GB.
I had three other mmos on my computer final fantasy 14 and Black desert on line.
I have lots of storage never had that problem loading anything down to my computer before.
Can anyone help me.?
I system indicates that I have 8 GB of RAM but I have tons of other memory.

Looks like the minimum required RAM is 16 GBs now.
I used to run it on 8 GBs but then that was back when Stanton Station was the only play area.

16 is the min and thast is the bare min.
I recommend at least 24 or 36 if you can manage it.

Personally run 48 and I have no issues.
