windows vista

can knytt run on windows vista and if so can someone show me how to run knytt or what version to get because i download the game but my computer keeps saying that the files are corrupted. 

Are you trying to run Knytt from the zip archive? Are you running it as an administrator, and/or is DEP interfering? How many times have you downloaded it? Have you cleared your cache before redownloading it?

Without more specifics, no one is able to help you.
