Unknown device type -- Try PCH

I'm using MPLAB 8.56 and I wrote this:

Code:

#include <18f4550.h>
#device adc=10
#use delay(clock = 8MHz)
#fuses INTRC, NOWDT, NOBROWNOUT, NOLVP
void main()
{}

After compilation:
Error 24 "C:\Program Files (x86)\PICC\devices\18f4550.h" Line 2(9,19): Unknown device type -- Try PCH

In the 18f4550.h header file it's written:
//////// Standard Header file for the PIC18F4550 device ////////////////
device PIC18F4550
#nolist
//////// Program memory: 16384x16 Data RAM: 2048 Stack: 31
//////// I/O: 35 Analog Pins: 13

So, I think the right device is included....... I don't understand what happens.

Go to the Configure / Select Device menu in the top right side of the menu bar in MPLAB. What device is selected there ? It must be set to 18F4550. You probably currently have it set to a 16F PIC.

Thanks, that's fixed. It works well.
