Newbie with this compiler, need to config PIC18F67K40

[Ecoli-557]

Hello All-
I am moving from PBP3 to this compiler and I want to configure my 67K40 for internal oscillator and at 64MHz.
I have used:
#Config
CONFIG FEXTOSC = OFF       ;External Oscillator not enabled
CONFIG RSTOSC = HFINTOSC_64MHZ       ;HFINTOSC with HFFRQ = 64 MHz and CDIV = 1:1
#Enconfig
which works under PBP3
I have tried this:
Config_Start
    Config FEXTOSC = OFF       ;External Oscillator not enabled
    Config RSTOSC = HFINTOSC_64MHZ       ;HFINTOSC with HFFRQ = 64 MHz and CDIV = 1:1
Config_End
However, the compiler barks at this and gives an error:
CONFIG Directive Error: (setting 'CONFIGFEXTOSC

Advice is needed

Just found the fuse configurator - will try that

Works Like a CHAMP!  Stanks!!

Good. It's a fantastic plugin, saves a lot of hair-tearing in my experience.

The fuse configurator is an excellent plugin, created by Johnb.

A standard program listing layout is shown below for a PIC18F67K40 device operating at 64MHz with its internal oscillator, and the OSC pins set as standard I/O pins. The same fuses can be used with all the 18FxxK40 devices:

A device's ".ppi" file contains all the valid fuses for the device, so it is also a good idea to look into that file. The compilers ".ppi" files can be found on the drive here: "C:\Program Files (x86)\ProtonIDE\PDS\Includes\PPI\", and the config fuses are located at the end of the file.

So for a PIC18F67K40 device. The default config fuses in the ppi file are:
