Free Trial Download Error

I am trying to download the free trial of Rhino 5 windows and after completion when I open the file, it tells me “File is corrupt.”

Any known reason for this?

Hello- at what point do you get this message? Does it get the the ‘unpacking’ stage or does it not run at all? I downloaded and ran the installer just now,and it seems OK here- you might make sure you have any virus checkers turned off.
