Thank you Finally some one who actually helpedThe picture with the download link shows it's the right file, but your other picture that shows the downloaded file as a word document don't show the size of the file. Can you confirm it's over 2GB in size?
If it is over 2GB then it's most likely the right file but word has made itself the default program to open rar files with. All you need to do in this case is to right click on the file and choose open with 7z and it should extract the rar.
