P: Edit In External Editor does not work/function

Same problem. Edit in external editor does not work.

Error message: Unexpected error performing command: bad argument #1 to 'lower' (string exptecte, got nil)

Same problem here. Windows 7 64-bit SP1, I have all Nik plugins but none is working, I get the same message "unexpected error performing command: bad argument #1 to 'lower' (string expected got nil)". It is not a Nik problem though, as any other external editor I had configured (Capture NX2 2.3.1 and FastStone MaxView 2.5) gives me the same error. Installing an evaluation version of PSE 10 solves the problem, all plug-ins can again be accessed through "Edit with" command, but if I uninstall PSE 10 the problem is back. Since I am told that LR 4 beta did not suffer from this problem, Adobe engineers may want to check differences between the installation procedures of LR 4 beta, LR 4 and PSE 10. Although bugs exist in any piece of software, I find shameful that such an evident bug was not found by Adobe before releasing its new major version of LR.

If Adobe is aware of thousands of users with problems with Lightroom 4, why don't they just pull it from the download site so that others don't get frustrated with the buggy program? Adobe, be honest and admit there is a major issue with the final release of LR 4 and hold off any more downloads and purchases. By not admitting the problem and allowing buyers to purchase a defective product is not an honest thing to do.

I am also having this problem of an unavailable "edit-in" in LR4. None of my Nik plug-ins are available - nothing happens when I select this menu option. Mac 10.7.3 and SEFX 2.004, all the other plug-ins for my Nik suite are greyed out.

oh and the PSE10 work around doesn't work either.

I am annoyed with Adobe as I have been a LR user since the first Beta and this is the first glitch experienced - I feel cheated having paid for what I thought would be a brilliant improvement e.g. 2 -> 3. Grrr!

I'm having the same issue. I'm using the newest NIK Silver Effects plugin but get the following error message when I try to "Edit in": "Unexpected error performing command: bad argument #1 to 'lower' (string expected, got nil)." This is a clean installation for me on a new hard drive and I haven't installed PS yet.

I have the OnOne plugins installed, previous to the LR4 upgrade, and they are still working for me as expected. But, these are accessible from the 'Plugin Extras' menu rather than the 'Edit in', so I presume that is still working...

I have a slight variation to this problem as well. My challenge is no Nik Plug-ins are available from Edit-in within LR4.

Running MAC OSX 10.7.3 and 64-bit kernel. Installed LR4. Have downloaded recent versions of Nik Plug-in's that support LR4. Some (not all), like Color Efex Pro see PS5 and LR4 during install, but the LR4 Edit-in menu never shows the plug-in. When I go to uninstall the Nik plug-ins, again, all appear available to PS5, and only some of the uninstallers see LR4 as if they are installed. LR4 is unusable with all plug-ins for me.

Would be great! best Idea and probalby would heal all the pain we all have due to inoperable LR;

I'd be happy if the bug fix was to give all LR users a free copy of CS5 😄

Waiting for the fix, no response from adobe??
cheers
my Observations I have made are these ...

There seems to be a missing component or even probably a 32bit compiled version for the 64 bit editions or some error in that component in the external plugin area of final LR4;
which can be healed with installing CS5 or PSE
