Problems installing the new patch to Battlefield v.15

[NiZire]

I'm trying to install the new patch v,1,5 (full one) and I got 1,0 from before, but when I'm about to isntall it says it cant find the game and I know it has to do something about that I recently formatted the harddrive Station C: and the game is on Station D: so I bet some registry keys is missing in the windows registry...

Anyone got a brilliant idea to add some keys or something ?

Re-install the game from CD.
