Install battlefield 4 from external hard disk to my hard drive?

[ClarenceThePro]

I dont want to wait long to download the game because my net is not always good.
So i have a backup of the game in my hard disk and i want to install the game from there without downloading.
But i cant because it gives me an error:
ERROR LAUNCHING GAME
The game blablabla does not appear to be installed. try installing or relaunching.
So if there is a way to do this i am waiting.
please no answers about patience .
Thanks

Copy the game to your harddrive.
Install Origin
Add the game location to the Library in Origin.
Launch the game thru origin.

Another way to do it is start downloading it and let it download 10MB or so, pause it and close origin. Then copy all of the files in the BF4 backup folder and paste them in Origin Games\Battlefield 4. Then boot up origin and click continue download, it should skip over it all and just download any updates if there have been any since you backed up.
