i think u are using asim khan ISP programming 3.0a
your LPT port connection pin 2 connect to pin 12 will solve this problem , 2 to 12 is to let ISP program verify which type of MCU are programing . i tested it working without any msg .
if you are using asim khan programmer then check this pic if ur (fuse bytes) command button is highlighted or not if that is not highlighted then your system is infected with viruses scan for viruses .
you should check whether the mcu is 89s52 or not,, bcz 89C52 is not programmed using asim's khan prog. or you should check your cable. or your burner may have problem.
