I have the creative cloud, and I really like it. However, I don't have a GPU in my computer. So the adaptive wide-angle filter doesn't work for me when using Photoshop CC 2015. I uninstalled Photoshop CS6 before I realized this problem. The adaptive wide-angle filter worked on CS6. So my question is, if I reinstall CS6 will it establish itself as my primary external editor in Lightroom? I just want to be able to designate it as my secondary external editor.
If you still have Photoshop CC 2015 installed on your computer, and once you reinstall Photoshop CS6 .
You would need to set Photoshop CS6 as the external editor , as Photoshop CC 2015 will be already set as the default editor.
Let me know if it helps.
