Same issue using Steam version no crack or anything. Tried mines, dropping the body from behind glass, waiting, reloading save, and other little things with no luck so far.
Kept trying and got it to work through glass as stated. What I did to get it to work was once the body was on the glass I backed up all the way by the store then moved left as far as I could and shot the body forward and BAM it scanned right off! Thanks a ton!

I can't get the thing to even scan whilst I'm behind the glass, is there a specific knack to stat as well?
