I have installed Exposure 4, and at the time I had LR4 and CS5. All worked as intended. Now I've just upgraded to CS6. What do I need to do to get Exposure 4 installed into CS6? I suppose I could just copy the plugin directories from CS5, but is there more to it than that?
Platform in this case is MacOS 10.8 (Lion, not Mountain Lion.)
It is never a good idea to move or copy plug-ins as you lose other file associations and potentially create more problems. Just send your license code to support and request an installer or download it here.
