Yes, it'll work with PPB but you still need a real device programmer to get the bootloader into the chip the first time.

With Microcode Loader comes a bunch of .hex files, matched for specific devices running at specific clock frequencies. You need to take the appropriate .hex file, use a device programmer (PICKit3 for example) and program the PIC with that file. Only from that point and only if you actually run the PIC at the clock frequency the bootloader file was built for will you be able to bootload the chip using the PC application.
