The G540 does NOT work with ISP. You have to remove the mcu from your circuit and put the mcu in the programmer. ISP is "In System Programming" and works with an ISP programmer and your application board.

Further, if you look on the list of supported devices, here:

http://www.pic16.com/soft/G540_DeviceList.txt

There is no Atmel mega or avr chip even listed. It WILL program Atmel programmable logic devices and memory, but no MCU. So, even though the heading to the product says:

G540 USB Universal Programmer for EPROM FLASH GAL AVR PIC 51

Either that headline is lying or the device list is lying. Based on the list of supported devices, this device is totally useless for any atmel mcu.
