Don't download it like that save it to your desktop because most anti viruses and Windows itself stops a lot of things running from the temp folder. It also could be that it's not fully downloaded and the rar file is corrupt so it won't let you open it. Your best bet is to CopyPasta that error in to google and have a brows around and see what others say. It's also very odd if it is in a rar/zip because it's already tiny.
Make sure you're also logged in on the administrator account if your on vista because it won't let you install anything. Your best bet it to try downloading it on another computer and see if it's just the file.
That helped me as well ty bud
