Hi,

Someone reported the following error message when launching Color Efex from LR 4 : "unexpected error performing command: bad argument #1 to 'lower' (string expected got nil)". Obviously a bad pointer passed to some function. Not sure whether he is using the latest vesion of Color Efex (currently checking this). No problem when running Color Efex from LR 3.6 on the same system.

Silver Efex Pro works fine in LR4, for which I'm thankful.

Win 7, 64-bit.

I can confirm Silver Efex Pro 2 won't start here under LR4 and OS X 10.7.3

I experience exactly the same issue - but on Win7 32 bit. Uninstaling Lightroom, NIK plugins didn't help at all.

Nik just updated their plug-in for LR4: http://www.niksoftware.com/downloads/usa/entry.php?view=software

Same problem here with PC

Windows 7  64 bit

Same error occurs after updating with newest NIK software updates.

What does NIK say, surely its their job.

IF Adboe has made some changes in their Plugin-Interface for the final version - I see some responsilbity too on their side.

what has changed in this area form LR4 Beta to LR4???

cheers

Just tried both Silver Efex Pro 2 and Viveza 2, latest versions, and both worked for me.

Oh well, I will try to d/l trial of Photoshop then and see if it helps.

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)". I think 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. More probably an Adobe problem, hope it gets solved quickly :-)

Nik plugins (Color Efex 3 and Silver Efex 2), OnOne plugins (PerfectSuite) and Topaz Labs plugins (Full suite) all exhibit the same error for me, as well on Windows 7 SP1, 64Bit. Error messaging is -- "unexpected error performing command: bad argument #1 to 'lower' (string expected got nil)".

No Photoshop versions installed, only LR4 at this point.

I just got off phone with NIK tech support.  They logged on to my computer and reinstalled everything again.  They said it appears that it is an Adobe issue and it seems to be the case.  I don't know what all he did, but he was all over my computer and checked installation, etc.  Was very thorough. 

ymc226:  NO, they said it was an Adobe issue as far as they could tell.

Windows 7 64-bit SP1 machine here.

Yesterday, as most of you here, I had this error message with any

external editor, and I posted a message in this forum. At night, before

going to bed, I installed an evaluation version of Photoshop Elements

10. This morning I opened Lightroom and, TADA!, plugins work fine! So

definitely it is an Adobe problem, LR must be missing some piece of

software that PSE has; note that I did not open PSE at all after

installing it yesterday night, so it has added the missing part during

installation.

Hope this helps Adobe engineers to solve the problem.

What you did just changed the memory layout for Lightroom and other programs. See this thread. The bug is obviously in Lightroom in any case but this kind of dangling pointer problem may or may not cause a crash depending on the random value stored in the pointer. Kind of a lottery. I don't think that PSE has anything to do with the problem.

Thank for your reply Samoreen. The interested thing is that changes

introduced by the installation of PSE only persist as long as you keep

it on your machine. I tried uninstalling PSE and the error in LR is back

again.

It is interesting to me that for sarki64, installing PSE10 solved the issue.  I uninstalled and reinstalled PSE10 and the problem persists for me.

I used LR 3 and upgraded to LR4 on Widows 7 (64 bits). I had no issue launching Nick soft (I did not update to their yesterday's editions. I have the previous ones). I was affraid that this stops running when I delete LR3. But I did it anyway (for the fun), and it does work with no problem.
