Battlefield 3: Armored Kill Downloads

Members greatly Hello!

The brother today from Lu X auction nets

Bought a BF3 PCgame

My home computer is W7 32-bit

I used the first disc download Origin

Not found inside the compressed file and then the second disc compression

So Origin into the CD-KEY

Origin to download

But it is written that "you must be logged on as an administrator to continue"

This computer I have something administrators! !

Run this program as administrator also use the right → → content → compatibility 【Origin】

How to do it! ! ?
