Hardware Error when installing a new library for ESP32

I am trying to install a library to drive a strip of LED’s, WS2812B’s. After downloading, unzipping, and moving it to the libraries directory, I try to install it using the library manager. I get the following error.

WARNING: Error loading hardware folder C:\ … \Arduino\hardware\espressif

No valid hardware definitions found in folder espressif.

Is there anyway to obtain more information about this error?

Internet searches are not helping.

This is using the Arduino IDE and it’s for a ESP32 Thing.

I’ve also re-installed the esp32 files after removing them. I’ve also made sure that I exited the Arduino IDE before I moved the library into the libraries folder.

I think you installed the new library in the wrong place. Remove it from the library folder where you have installed it. Now check that ESP32 can start correctly. If not, reinstall the ESP32 again. If that works, now leave the zip file for the strip led library in downloads, do not unzip. With the IDE menu, select sketch, include library and find the zip file. It will now be installed correctly.

Very much appreciated. Thanks.
