This is the Lightroom forum. But what plug-ins are you talking about? And, what program and version are you referring to?
When I subscribed to the creative cloud and installed Photoshop 2014 CC I had to copy folders from the plug-ins directory in Photoshop CS6 over to the plug-ins directory in Photoshop CC. Once I did that my plug-ins were available and usable.
Yes, Sorry for the rant... I was right in the middle of a project when I updated to LightRoom to 5.7. I found out that once doing so, I had lost the ability to right click and use the EDIT IN feature... ie: EDIT IN Photoshop CC or Photoshop 2014 CC or any of my NIK plugins.
I read a link on Adobe's site to fix this:
I followed the process for Windows Solution 1 (did not want to jump into the registry)... which says to uninstall PS. So I uninstalled and reinstalled... Still not working... EDIT IN options are still grayed out.
Any suggestions as how to fix this? Thanks
