My appologies, you will need this as well.
It has come to my attention to open the file you will need https://www.7-zip.org/download.html to get going you will see a ReadMe follow it's instructions, then after that you will need to do 1 round only of a basic .zip file using what you normally use to open the file, then from there just use the setup (Application) it will further more deal with the last set of stuff! I never realized how semi complicated the steps were until I just had to explain to someone who Purchased/Downloaded the game! But now you know the steps! Sincerely, Sarainia Angelsong ... and Cheers! Enjoy! :)
