The .rar file is not the game itself but its a type of archive file. You will need a program that can extract .rar files like Winrar for example. Everything you need will be found in that archive.
I did try to extract it using an app from the Microsoft store but al It gave me was the music files from the game. (also thx for replying)
Not the creator, but it sounds like you might’ve downloaded MemoirsOfMagicOST.rar rather than MemoirsOfMagic.rar (OST stands for original soundtrack)
