I cannot get a successful program on any Microchip PIC18F4520. I have tried many different versions of your software with Windows 7 32 bit and Windows 8.1 64 bit. Can you please help me....

Can you send me the configuration settings that you are using so I can compare them to mine. I can successfully program these chips with a SmartPRO X5 programmer but not with the VP-498 so far.

During programming the device data and buffer data do not match and the operation ends. There is no specific error other than that.

I followed your suggestion to change the tPW setting to 6 and retried the operation but got the same failure at the same point in the process.

Did not work. It seems that it is putting the data from the buffer into locations 01H and 02H at which point the verify catches the error.I will email a screenshot of the read of the device after the failed programming so you can see for yourself.
