How can i fix this error

Hello dear, I want setup important software from disk but I cannot install it. Many times I try but all times I failed.
What’s problem, I don’t understand?
I uploaded an image for you.Error message is
"Error 1335.The cabinet file ‘Data1.cab’ required for this installation
Is corrupt and cannot be used.This could indicate a network error, an error
Reading from the CD-ROM,or a problem with this package".
Please give advice, how can solve this problem and how can I install that software?
Thank you
