Defective Efex

My copy of Silver Efex Pro has stopped working. What can I do? Lara Pooley

AI’m guessing you downloaded it when Google was giving it away for free. While this was great, it also meant that Google wasn’t updating it and keeping it compatible with the latest versions of Photoshop or Lightroom.

It’s changed hands now, and has been taken over by DxO. The good news is DxO will ensure it works with these other programs; the bad news is the new DxO version costs money! Get the trial from www.dxo.com first to check that everything works.
