SLI, can't for the life of me get it to work

[Smeghead_3]

Just last week I purchased another GTX680, Ive spent the last few days going through all my games and finding out which work better with SLI and which dont.

IL2 COD is the only one in which I've had no success, it simply refuses to even attempt SLI.
I am computer literate and have been using nvidia inspector since I got my first 680 a year ago.

I followed the instructions here

but SLI doesn't seem to attempt to run.
Ive also tried creating custom profiles as I've had to do with other games but no success. I wouldn't mind so much if it ran SLI but not very well, but it just doesn't even attempt to run.
Hopefully I am missing something obvious but just can't see it.

any help appreciated

thank you
