The rar file is fine, it extracted and works ok to me. Windows built in unzipper is trash for RARs, you need to use a 3rd party tool to unpack it, I use 7-zip, but even with 7zip you can't just double click it to open it, you have to right click and select 7-zip > Open Archive
I've converted it to a ZIP file and attached it here for you.
