Pl2303 Eeprom Writer Utility Software

HI, OK, I have spent quite a while with this now and I can confirm that my laptop and desktop are both doing the same thing. I programmed a chip (16F628A) without code protection using MPLAB and PicKit 3. The chip programmed and verified. I then read the chip using your software and board - the read looked good as far as I can tell. Using a second chip I erased it and then attempted to program it using the code I had just read from the mplab programmed chip. It generated the error at the end indicating that the EEPROM had a problem.

Using the laptop and desktop side by side I can confirm that the flash code looks good but the EEPROM has not programmed correctly - exactly as the error reported. I also tried it with a different USB cable on the laptop, result was exactly as above. If you are able to read the devices ok then this narrows it down to a programming issue.
