Hi Wang,
No idea.
I don't have a DZ60 for testing. I have tried similar devices (DZ128 & DV60) and they both work well.
Can you provide information about :
You can try running the debug version of the programmer
HCS08_FlashProgrammer-debug.exe
which will create a log file:
$APPDATA%/USBDM/FlashProgrammer_HCS08.log
which might have some clues.
bye
