AI models are downloading please try again later.

I get a popup telling nme that “Some AI models are doiwnlaoding. Please try again later” - it’s been at 51% for 4.75 hous!

​@Sameer K the fixes you suggested do not work. I don’t understand how AI is now preventing me from using presets that I purchased years ago and it is obnoxious that LrC is unusable. I am on the latest version and running windows 11. 

Lightroom 15.6. Windows 11.  Yesterday this problem did not exist. I have not changed hardware or software, but suddenly I am getting “some AI models failed to dowload”     everytime I try to do a selection or Preset.  Administrator mode makes no difference.  Surely Adobe should be using AI to find why paying customers have to put up with this?

I’m on Windows 11

I have tried all the remedies suggested above and still getting a red popup saying “Some AI models failed to download. Please try again later.” since updating to 15.6 release

@sameer

This is heronsong.I am having this problem since installing Lightroom Classic 15.6 release. I have tried everything I could find including reinstalling the app. There is nothing about Adobe (or anything else) in the hosts file. A couple of times I have gotten :”Some AI models are downloading” It always stalls at 70%, after which I’m back to “Some AI models failed to download”.

I updated from version 14 to 15.4. Unfortunately, the AI presets aren't working after I launch the program. I always get the message: "Same AI models are downloading. Please try again later. Downloading 0%" and it stops.
Is there anyone who can help me? Where should I ask?

The cause was that Adobe domains were being blocked in the Windows hosts file. Here is what fixed it:

1. Search for Notepad in the Windows Start menu.

2. Right-click Notepad and select “Run as administrator.”

3. In Notepad, go to File > Open.

4. Open this file: C:\Windows\System32\drivers\etc\hosts

5. Change the file type from “Text Documents” to “All Files” so the hosts file becomes visible.

6. Search for “adobe”.

7. Delete any lines containing Adobe domains, especially entries pointing to: 127.0.0.1 0.0.0.0 For example: 127.0.0.1 adobe.com 0.0.0.0 ims-na1.adobelogin.com

8. Save the hosts file.

9. Open Command Prompt as administrator and run: ipconfig /flushdns

10. Restart Lightroom Classic.

After removing the blocked Adobe entries, Lightroom was able to connect to Adobe servers again, and the AI masking models downloaded successfully. Make sure you only remove Adobe-related entries and leave unrelated hosts entries unchanged.
