Hi there,
I had to reinstall Lightroom classic on my iMac today and when I tried to install NLP it simply didn’t show up in my plug in screen in Lightroom, although the installation seems to be “succesful”
I’ve been a user since half a year now and everything went fine, never issues, even with updating a while back, until today.
Any tips?
Did you run the NLP installer too while Lightroom was not running? The NLP Mac installer does a few things that might have been overwritten by the LrClassic re-installation.
From the NLP Install Log
- Installing custom camera profiles to /Users/USERNAME/Library/Application Support/Adobe/CameraRaw/CameraProfiles/NegativeLab Camera Profiles/
- Installing enhanced settings to /Users/USERNAME/Library/Application Support/Adobe/CameraRaw/Settings/NLP Enhanced Settings/
- Installing custom camera profiles to /Users/USERNAME/Library/Application Support/Adobe/CameraRaw/CameraProfiles/Vuescan Profiles/
- Setting up negative lab shortcut key [ctrl + n]
- Adding shortcut key for Lightroom Classic CC
- Adding Negative Lab Plugin to following directory: /Users/USERNAME/Plugins/
TO FINISH YOUR INSTALLATION
- Restart Lightroom
- Go to ‘File -> Plugin-in Manager’, then click the ‘Add’ button
- Select ‘NegativeLabPro.lrplugin’ and click ‘Add Plug-in’. If you don’t see it, navigate in the dialog box to this folder: /Users/USERNAME/Plugins/
- If you’ve already purchased Negative Lab Pro, add your license number and click ‘ACTIVATE Negative Lab Pro’ (otherwise, you can take Negative Lab for a test drive in trial mode)
Notes:
“USERNAME” is used in stead of your account name in the transcript.
I use /Users/USERNAME/Library/Application Support/Adobe/Lightroom/Modules/ for the plugin. Most Lightroom plugins are installed the the Modules folder…
Yeah I think I might have had LR open while running the NLP installer… What should I do?
Close all applications, restart your Mac, log in and then install NLP again.
Follow the instructions usually helps 
(Restart is not necessary, but it never hurts to reboot every now and then)
