Battlefield 4 not showing on origin and how to change installation path folder

As I mention on the title, I bought battlefield 4 from a local video club and redeemed the code to origin. After the redeem, I went to see if it was on my games list, but it wasn't. I tried again by going to recently purchases but nothing again. Another problem : How do I change the install folder....  When I put the disc in the pc and start the autorun.exe, it sais step 1 : install origin(which I have already installed), I press continue and an error pops up generally saying that there is not enough disc space, and yes, I do not have enough disc space on C:/ but there is enough on D:/, so how do I change the path folder ??

PLEASE HELP ME !!!!!!!!
