Hi @chuck659
Please provide a detailed description of what you mean by "does not install".
Did you see an error message when you attempted to install the library? If so, please provide the full and exact text of the error message.
I just installed the library and all dependencies without any problems using Arduino IDE 2.3.4. It did take a painfully long time to finish. The main reason is that the "M5GFX" library dependency is a ridiculous 137 MB. Although not as significant individually, it also must install the relatively large "U8g2" (46 MB), "ESP8266Audio" (21 MB) and "FastLED" (20 MB) dependencies. So it takes a significant amount of time to download and extract these libraries.
