Old version. Latest is 5.11. Download MPLAB IDE v 7.61 (maybe 7.62 by now)

I forgot to mention that I use MPASM 5.03 assembler, because PM does not have inc file for 18F4431 ( or does it ? )
PM does NOT support 18Fxxxx.

3.b. When using Microchip's (MPASM) Assembler
If you're going to use MPASM, look for the appropriate file (example for a 16F628 look for P16F628.INC) located in something like the MCHIP_Tools subdirectory of your MPLAB installation. Here you’ll find the Configuration Bits located near the bottom of the list. Simply just use the ones you want. Hey presto your PIC is all defined and ready to run.
But how ? I am new to PBP, please help
Edit the file using WORDPAD, NOTEPAD, or any other pad you can find, comment out the config bits you're NOT wanting and un-comment the rest.
