What is the problem ?
Is it that FastLed.h cannot be found ?

Post the code and full error message, if any, not a picture of part of it

Why are you using an hourly build of the IDE ?

Invalid library found in C:\Users\С М У\Documents\Arduino\libraries\sketch_feb18c: no headers files (.h) found in C:\Users\С М У\Documents\Arduino\libraries\sketch_feb18c
Invalid library found in C:\Users\С М У\Documents\Arduino\libraries\smu: no headers files (.h) found in C:\Users\С М У\Documents\Arduino\libraries\smu

Delete the folders in the libraries folder that do not contain libraries.

The error message tells you which ones they are

I deleted everything from the library

Please read the forum guidelines especially #7 & #11.

Do this:

  • (In the Arduino IDE) Sketch > Include Library > Manage libraries
  • Wait for the download to finish.
  • In the "Filter your search..." field, type "fastled".
  • Press Enter.
  • From the list of search results, click on "FastLED by Daniel Garcia".
  • Click the "Install" button.
  • Wait for the installation to finish.
  • Click the "Close" button.

After that, the errors should no longer occur.

Terrific.

If you want any help with your code, you need to begin paying attention to the many requests for information that have been posted here. Begin with posting your code, in code tags.

Ok thx

The error is caused by the Cyrillic characters in your sketchbook path: С М У
Ideally, these characters should be supported, but I don't know if there is any way for you to accomplish that. I seem to remember an existing bug report for this. I'll try to dig that up later today.

For now, my suggestion is for you to use a sketchbook folder that has a path with only ASCII characters. So do this:

  • Pick the Arduino sketchbook folder you want to use (that doesn't contain Cyrillic characters anywhere in the path). This folder will be used to store the Arduino libraries you install, and also is a convenient place to store your sketches (though you are welcome to save sketches in other folders if you like).
  • Create the folder if it doesn't exist.
  • If you like, you can copy over the files from your previous sketchbook folder (C:\Users\С М У\Documents\Arduino)
  • (In the Arduino IDE) File > Preferences
  • Click the "Browse" button to the right of the "Sketchbook location" field.
  • Select your new sketchbook folder.
  • Click the "Open" button.
  • Click the "OK" button.

Repeat the installation instructions I provided in my previous reply:
