Just got a new iMac with macOS 15 Sequoia. Downloaded the latest version of NP. Put in my key, no luck. Discovered the key was for the 2.1 version. So got rid of the new version from the plug in list in LR. Downloaded the old 2.1. Train and installed it. Went to the plugin list and clicked on it. It took my key. But when I tried to add it to the plug in list, came up with an error that you can see in the attached image. I’m running the newest version of LR. I did the Rosetta install too. Help? ---

Welcome to the forum @Gaaslaj When you scroll down, will the _Status_ section show two _buttons_? If so, click the one that says “_activate_”. BTW, you might want to hide your license key in your screen capture. ---

I fixed the problem, just needed to enable the plug-in! Thanks, John.
