Hi Nate,

Recently purchased NegLabPro but until now I’m still stucked with activating the license key. Hope you could help me out on this one.

Here’s the list of activities that I’ve already made.

  • turned off firewalls (license key activation unsuccessful)
  • turned off and remove other antivirus program (license key activation unsuccessful)
  • re-installed my lightroom CC (license key activation unsuccessful)
  • installed a VPN for the sake of trying even I’m from Singapore, (license key activation unsuccessful)
  • copy paste directly from email (license key activation unsuccessful)
  • verified already for spaces and other extra characters during copy/paste

Until now I still keep having this ERROR: Could not connect. Check internet connection and turn off firewalls.

running windows 7 ultimate
lightroom classic version 9.4
neglabpro 2.2

Hi there

I’m trying to fix the absolute same issue. Been using NLP for over a year on my old Windows machine without problems. Now got a new Computer and can’t activate my NLP-Key. First, I get the message “Authorizing… please wait”, but nothing happens. Then, I try again a couple of times, befor it says “cannot connect”. No Firewalls active at that time. Any ideas anyone?
Cheers

I am also having this problem! The trial works fine, but when I put the license key in, I get a “Could Not Connect” error.
My setup:
Windows 7, 64 bit, SP1
Intel core i5 650, 3.2 Ghz
12 GB RAM

NegativeLabPro V 2.3.0b

It is the same, firewall on or off. This computer is rarely used on the internet, and only uses Windows Defender for antivirus.

+1 for exactly this issue.
@stanley, @NX211 did you manage to fix it?

Something was fundamentally wrong with my adobe installation that even trying different versions didn’t work. I had to format my computer to fix my issue.

I am having this issue. Is there a fix yet?

I used the trial of NLP 3.1.1 and am using Lightroom Classic 14.5.1 on Windows 11 Pro 24H2.

Update: I noticed the invoice was for 3.1.0, so I downloaded and installed that, but got the same error. After a few minutes though, it allowed me to activate. Perhaps the key was generated but took a moment to get added to a list of valid ones in some backend database? Shrug.

Had the same problem today on trying to activate my license on Windows. Turning off Windows Firewall for the moment during activation solved this for me.
