Hi cHud, Thanks for the response. To answer your question, yes there is a *.vdz file present in the CF card. File name : Z524SE-0.VDZ As additional information, I suspect that the purchased Touch Panel is not a new one. I'm not really sure but during start-up there is already a program that executes when the unit is turned-on. Here's what we have done to simulate what you have inputted by using a USB flash drive. 1.0 Removed the New CF card. Copied the files on the old CF(running and operational) card to a USB flash drive. 2.0 Inserted the USB flash drive to the Touch Panel. Power on the Touch Panel. Result : The program executed is different from the program. It is of Chinese characters. This is the reason why I suspect that there is a program already installed in the Touch Panel. My addtional questions. 1.0 Are we going to use the Video designer to remove the installed program? 2.0 Can we configure the touch panel so as to run the program present on the USB flash drive without using the Video Designer. - I asked this because we have not purchased a Video Designer yet. 3.0 Is it possible to change the default language to English instead of Chinese using the touch panel only? thanks and regards, Arnel
