I liked the free Google price better and wish I hadn't deleted the .exe files. But I can spring for $50 if need be. Hopefully, DXO fixed the issue of it hanging sometimes (too often) when it passes the altered Nik file back to Photoshop. If you have this issue, the solution is to go into whatever app in the Nik suite and under "setting" change "create new layer" to "use original layer" (or something like that -- you'll know it when you see it...) Nik hangs sometimes (too often) when it tries to create its own new "Nik" layer in Photoshop. Disabling this option in each app in the suite's settings corrects this but it applies the changes to the original layer. Suboptimal solution but it's much better than having to stop Photoshop in Task Manager.
