Stuck on first attempt using MPLAB X

[Demon]

SOLVED: Result in post 35.

SUMMARY:

- no SPACES in folder and file name.
- use IPECMD.EXE with command line options (read CommandLineReadmes in C:\MPLABX\v6.05\docs for details).
- use W command line option when PIC is powered by programmer, this was probably the most important thing, my PIC wasn't powered.
- use tool serial number or generic name in command line.

Trying to get a simple program working using PBP3, MPLAB X with PICKIT4 and a 16F877 on the Lab X1, but keep getting:

make -f nbproject/Makefile-default.mk SUBPROJECTS= .build-conf
make[1]: Entering directory 'C:/PBP3/Test_programs/Test1_16F877_LabX1'
make[1]: *** No rule to make target '.build-subprojects', needed by '.build-conf'. Stop.
make: *** [.build-impl] Error 2
make[1]: Leaving directory 'C:/PBP3/Test_programs/Test1_16F877_LabX1'
nbproject/Makefile-impl.mk:39: recipe for target '.build-impl' failed

BUILD FAILED (exit value 2, total time: 104ms)

.

REM   ASM

#ENDCONFIG

DEFINE  OSC     20

TRISD = %00000000

LED0    VAR     PortD.0

        LOW LED0

START:  HIGH    LED0
        PAUSE   500
        LOW     LED0
        GOTO    START

Finish: end

I converted ASM to CONFIG, but that didn't help. I've used that youtube video to include the compiler in MPLAB X, that went super well until I tried an example.

Does our code have to sit in a special folder now?

I read that PBP3 migration PDF, can't see what else I forgot. I'd really like to stick with MPLAB and not return to MCSP+.
