Not sure how far you've got in eliminating candidates.

You have locked candidates (4) in row 8 as well as box 9
Again, locked candidates (5) in box 9
Now you should be able to place a few numbers.
If you get stuck again, look for an x-wing on 9s.
From there, it just unraveled with hidden and naked singles.

Numbler (http://www.axcis.com.au/numbler) finds as a first step "Box Row @ 9> r9c2 r9c2=2 r9c3x4 r9c3x5 r9c6x4", so box 9 has 4s and 5s only on row 9 so they can be eliminated from other cells on row 9. The solution is simple from there with no x-wing needed.
