Hello! I'm pretty sure you either do not have Winrar installed, or if you do, you need to right click this file, and click "Open With" and then choose Winrar. Most likely you tried to open something as a Word document, and Windows set it to default for all files that's similar. If this happens to this download only, then, I'm out of ideas!

Guessing for whatever reason, you or any of your family members that use your computer probably told Windows that 'the default way of opening .rar files is through Word Document' rather than through something like winzip or winrar. Right Click file > Properties and just Change what it Opens With.
