Once the handle has been removed, you should then be able to see the screws holding the lock to the frame. Once the screws are removed, you may try to grab the bolts with a wrench or pair of pliers. If this does not work then you can place the tool between the frame and the window (the gap could be different at each end of the windows) and make an "u" shape with your hand to grab the bolts.
