I found core-1.4.0 and delete. but this message says the opposite i dont have another files which contains name "core" or "arcore"
Hi, I've tested the behavior on 8.3.8 and after deleting the ARCore the info message disappeared. Switching it back to Required created a new message that the file is not available. The system checks to see if there is a file or not. Could you please confirm your OS? windows or macOS? could you go in the Project files and check under Assets/Plugin/Android and confirm if that the arcore file is deleted. Thank you.

Hi @jedai747 In the meantime I tested also with Vuforia 8.3.8 and Unity 2019.2.3 on Windows and after deleting the ARCore library, the .aar file, the message disappeared, I was *not* able to reproduce the issue. I should have been more specific with my request. I was referring to the actual Project location stored on your local HDD/SSD. When you navigate do the Project under Assets, do you still see the .aar file? Based on the tests that I have performed, the mechanism to detect the file is working as expected, I believe there could be a permission issue and Unity does not delete the file from your project. Thank you. Vuforia Engine Support
