P: Edit In External Editor does not work/function

My new LR 4 does not open my plug-ins. The previous version - LR 3 - still opens them. What is the problem?

Lightroom 4 error in Edit in. None of my plugs in work, reports error. Also when I installed LR 4 the LR 4 Beta was deleted and uninstalled, I do not have Photoshop. I am running a Windows computer with Windows 7 64 bit OS. This problem has affected thousands of users from what I can see. When are you going to correct the bug?

Maybe it is the data in the plist itself. The KB article did not mention any other check Lr does so I have kind of run out of ideas to try and fool it. Unless it looks for the physical installed files

The last one I can think of (if someone has the time lol) is to:
1) install Trial CS5 copy the plist file and move it in a safe directory somewhere. 2) Then uninstall CS5 and verify the problem retuns.
3) Then go back in and paste the saved Plist file back where it should be (without installing CS5) in the library
4) Check and see if that did the trick.

However there could be a flaw to this reasoning. Because Mac has a much more friendly Resigistry it could be that the data in the plist files themselves are changed as needed, when needed, for programs to pass information to each other. I think this is indicated in the above list where some Plist files are listed as being "rw" possibly meaning Read/Write access?

Unfortuanly if this is the case not much anyone can do except wait for adobe. Can only wait and see what next week brings, but hopefully they havent shipped the physical disks yet as it would be unfortuatly no advantage to have the flawed DVD except for the nice box and DVD holder.

I am having the same problem on my IMac.... Lightroom 4 gives no response whatsoever to attempts to use Elements10 as external editor.
Since Lightroom 3 is working just fine on the same machine, the problem is obviously in Lightroom 4 ! When is Adobe going to fix this?!

Just for information : On my Windows 7 64 bit system an uninstall of Photoshop Elements 6 and re install of same fixed the problem.

Well, this bug is now tied for first place in terms of most commonly reported with 55 votes:

A dubious honor for those of us suffering from it, to be sure. But, if you haven't already, please go to that index page and click on the star so your "vote" is counted. Maybe Adobe will take more notice of our ever-growing group if we stay on top of the list. 😉

One more to count:

Mac OSX 10.7.3, LR 4, PSE 9, Nik Silver Efex Pro, Noise Ninja

I'm also having this issue.

LR 4 and the newest versions of the Nik Software suite. Using the "Edit in" command does nothing, Lightroom doesn't even try to launch them.

(I'm running Mac OSX Lion)

Thanks JullieM & Karl...doesn't look like there is anything extra...bummer. Thanks for the quick response though. It's much appreciated
