All "Edit In" choices are greyed out, including PSCC 2015. Other external editors like On One and Nik show up but are greyed out. My copy of Lightroom 4 everything is OK. Help please.
Thanks in advance.
Please check and make sure the image you trying to edit is not missing from Lightroom.
You can re-link the missing in Lightroom refer: How to find missing photos in Photoshop Lightroom
