Project of DC2456A (Demo board of LTC3779) in your website cannot be opened

Dear sir,

I down load the design files of the DC2456A from https://www.analog.com/media/en/evaluation-documentation/evaluation-design-files/DC2456A.zip

The .asc file cannot be opened with error below. Could you please send me the right design file? And could you please explain the function of each file in the .zip file?
