Hi folks. I tried converting black and white negs for the first time today and had this message. Does anyone know how to resolve please? Thanks! ![Screenshot 2020-12-19 at 20.33.55](https://canada1.discourse-cdn.com/flex029/uploads/negativelabpro/original/2X/b/b3d05a7fc016caa140c01580e2f36a7cedef3fbb.jpeg) ---

Looks like an installation issue. _Mac_ screenshots and NLP asking for something from the _Windows_ download. While it is possible to manually install NLP on a Mac using the contents of the Windows download, a few things can go wrong. In order to work properly, the plugin needs to be a) read/write accessible by the user and b) present where Lightroom’s module manager has registered the plugin… ---

Thanks for that - much appreciated. I seem to have loaded a mix of the Mac and Windows trial version on my Mac (old age is a terrible thing). I bought the full version and had issues finding in in Lightroom. I found some mention (I can’t recall where) of how to find the plug in on a search and attach it manually - how is this done again please? How do I fully uninstall, so I can reinstall please? I think I need to hit ‘reset’. Cheers Steve ---

> [@DWW](#): > > How do I fully uninstall, so I can reinstall please? Hard to say, because I have no idea where you’ve put things. You might want to check the pages about installation and update: > **[Guide | Negative Lab Pro](https://www.negativelabpro.com/guide/)** > > Learn how to use Negative Lab Pro in Lightroom to convert and edit your color negative scans. Try running the Mac Installer again. At the end, you get a window with text. Select the text (cmd-A) and paste it to a Textedit document for reference… The installer script mentions the following places where NLP puts stuff: **LIGHTROOM DIRECTORIES** 1. ~/Library/Application\ Support/Adobe/Lightroom/Develop\ Presets 2. ~/Library/Application\ Support/Adobe/CameraRaw/CameraProfiles 3. ~/Library/Application\ Support/Adobe/CameraRaw/Settings **ATTACHED DIRECTORIES** - PROFILES=NegativeLab\ Camera\ Profiles - VUESCANPROFILES=Vuescan\ Profiles - PRESETS=NLP\ Enhanced\ Settings - XMPSETTINGS=XMP\ Settings Try to find the places mentioned above for the cleanup ---
