Some time ago, Microchip had an error in the P18F4550.inc file.
It was corrected in subsequent versions, so you are probably using an older one.
From the file ... C:\Program Files\Microchip\MPASM Suite
Was originally spelled ...Code:; these are correct _FCMEN_OFF_1H EQU H'BF' ; Fail-Safe Clock Monitor disabled _FCMEN_ON_1H EQU H'FF' ; Fail-Safe Clock Monitor enabled
You can just correct the spelling to fix the error.Code:; these are not correct _FCMEM_OFF_1H EQU H'BF' ; Fail-Safe Clock Monitor disabled _FCMEM_ON_1H EQU H'FF' ; Fail-Safe Clock Monitor enabled
And you should not be renaming MPASMWIN executables.
