IR REMOTE CONTROL file not found

Hi there, pardon for my English.

Recently I bought an IR Remote Control, and have tried various coding. Yet all of them came out as
"exit 1, IR Remote Control file not found"

Please help, thank you very much

When you encounter an error you'll see a button on the right side of the orange bar "Copy error messages". Click that button. Paste the error in a message here USING CODE TAGS (</> button on the toolbar).

My apologies.

Arduino: 1.8.5 (Windows 10), Board: "Arduino/Genuino Uno"

C:\Users\izzy\Desktop\ir\ir.ino:1:22: fatal error: IRremote.h: No such file or directory

#include <IRremote.h>


exit status 1
Error compiling for board Arduino/Genuino Uno.

As a side note, I've googled a bit and one method is to remove a C file and h file from the IR Remote library. However, even after removing the files it still shows the same error.

Usually that error means that you have not installed the library or installed it incorrectly.

If you installed the library, how did you install it?
