I downloaded NIDAQ850[0].exe and DeviceDoc850[0].exe, but when i tried to open these files in a windows vista system, then appeared this error message: "Zip file is damaged, truncated, or has been changed since it was created. If you downloaded this file, try downloading again.", i downloaded the files again, but i get the same problem, so i used a file repair program to fix these files but it doesn't work, so i don't know the reason for this message, i read a similar topic but i don't understand the answer.
thanks in advanced
PD1: excuses by my english
