I just bought Black Ops II on Steam, but I'm having trouble at this point. I saw a similar post on this website about Modern Warfare 3 (I'm unable to specify which Steam library I want to install MW3 to) where the option to install to a separate drive ceased to appear, but the selected answer (creating a symbolic link to the preferred drive) didn't work for me. I did attempt to change the command to fit my situation (C: being my SSD, D: being my HDD):
mklink /D "C:\Program Files (x86)\Steam\steamapps\Call of Duty Black Ops II\" "D:\SteamLibrary\Call of Duty Black Ops II\"
And I then tried installing Black Ops II from Steam, but it still recognized that there wasn't enough space on my SSD and wouldn't install it. I'm quite at a loss about what to do now. Keep in mind that my HDD is already completely set up as a separate drive, and many of my Steam games are already installed to it.
