Unknown device type "18F2450"

I get the following error message when I try to build my project:
--- Info 300 "D:\Clients\In10did\Projects\In10did\PIC18F2450 Source\18F2450.h" Line 2(9,15): More info: Device database: "E:\PICC\devices4.dat"
*** Error 24 "D:\Clients\In10did\Projects\In10did\PIC18F2450 Source\18F2450.h" Line 2(9,17): Unknown device type "18F2450"

When I build a 16C745 project I have no problem.
When I run CCSC +Q from the command line it does not list any 18F parts.

Most likely you have a compiler package which doesn't support PIC18 processors.

CCS sells different command-line compilers for the different PIC families:
- PCB: for the PIC12 series
- PCM: for the PIC16 series
- PCH: for the PIC18 series

Then there are compiler packages with a Windows environment:
- PCW == Windows IDE + PCB + PCM
- PCWH == Windows IDE + PCB + PCM + PCH

To check which compiler package you have you can execute 'CCSC +v'

'CCSC +v' list both PCM and PCH

The problem was that I had specified #DEVICE 18F2450 and it need to be
#DEVICE PIC18F2450

You should never have to type in that statement. You just "include"
the header file for the PIC in your program. The header file contains
the correct #device statement for the PIC, as well as all the constants
used by the built-in CCS functions. This example shows how it should
be done:
