Downloading elf for the Control Panel to DE2 Dev board Failed

[Altera_Forum]

Hi, 

 I'm attempting to use the Control Panel that comes with the DE2 education and development board but when i start up the executable, i get the error message...."download elf file (DE2_ControlPanel.elf) fail!". The programmer in Quartus recognized the DE2 and allowed me to downloaded the .sof to it successfully. I have no idea why this error message is happening. Any help is much appreciated.   Rob

On my Quartus 12.1, none of the control panels work. On my friends Quartus 9.0, it does.  Thinking about it, maybe the drivers supplied with the various versions of Quartus are different...... I shall experiment with this some time in the future unless someone does it before me.
