As per the screen shot you have given here, There are Three possible problems.
1. The chip is not good.
2. The Supply to the programmer must be Preferably AC-15v through Wall adaptor. SMPS will not work and give the problem with verify. Drop in the adaptor supply will result in verify fail.
3. The zif socket and the Micro pins are not connected well due to oxidation.(may be a old chip or a ZiF socket)

Your problem must be solved within these 3 possibilities. Helped you?....Good luck

If you can program other devices and not this particular device, there may be some problem with this micro. Use a new one and see the voltages are in the range given in my last post. Good luck
