Can't open NLP anymore (AutoColor 2.0 analysis required)

Hi there,

I was using NLP (v2.3.0b) without any problem until today.

Now i have the message “AutoColor 2.0 analysis required / You must unconvert then reconvert this image to enable AutoColor 2.0”.

It appears on any picture if I try to launch NLP. It happens on pictures already converted and on pictures not converted. I can only click OK but it doesn’t bring the interface.

I am on Mac (10.13.6 ) with LR Classic CC (7.0.1) and nothing changed since this bug appeared.

I tried to reinstall NLP but it doesn’t change anything.

What can I do?

Thanks

Hi @Francois1

  1. Can you go to “file > plugin manager” and scroll down till you see the version number of Negative Lab Pro. Can you confirm that it says “Version 2.3?” If you are upgrading from a previous version, it may be possible that it is still inked to the prior version.

  2. Can you confirm that this still happens even if you only have 1 image selected (and not a group of images)?

  3. Can import a completely new negative into Lightroom, and see if you still receive this error?

  4. Are you able to upgrade to a new version of Lightroom Classic? It’s possible that 7.0.1 contains bugs in Lightroom’s SDK which were later fixed.

HI,

  1. Yes 2.3

  2. Yes it happens even on 1 picture selected

  3. If I import a completely new negative in LR, NLP is opening fine.
    It looks that the problem happens if I try to open NLP on a picture that was already converted with a previous version. After getting this error once, I have it every time I try to open NLP on every picture. I have to restart LR to be able to launch NLP again.

  4. I can try to upgrade yes

Hi,

I have updated LR to 8.4.1 but it didn’t change the problem. There is still some pictures that brings this message and I have to restart LR to accces NLP again. The only workaround I found is unfortunately to delete and reimport the problematic pictures.

Thanks @Francois1 for your answers.

  1. Can you confirm if this happens in while in the “develop” module? Or if it only happens while in the library module?

  2. Can you select an image where this is happening, and go to “file > export as catalog” like image below, then email that full catalog zip to me at nate@natephotographic.com? This way, I can take a look at the metadata, and see what is going on.
