I am trying to use an action and I keep getting the message: The Command Lighting Effects is not currently available. I am using Photoshop CS5 on a PC. Does anyone have any suggestions about what this might mean?
OK, so maybe I didn't word my question precisely -- I do understand what the words "not available" mean. The issue was that I didn't know why it wasn't available. The second part of your answer seems to have actually given me the info I was looking for -- indeed I am running Photoshop 64-bit. I just saw on the NAPP site that in the new CS6 version this should not be a problem very soon.
Actually the windows cs5 64 bit version should have Filter>Render>Lighting Effects.
Did you look under Filter>Render>Lighting Effects to see if the filter is there?
Perhaps the action itself is at fault or the documents color mode and/or bit depth doesn't support the lighting effects filter.
