Why do you think the folder is empty? Maybe it is used while downloading.
Also, why do you put installation in a folder named Desktop? Is your Username Desktop? Did you ommit the /username/ in the posting? But that would mean you install exe on your actual Desktop folder. That is not to be done. Desktop is designated area for shortcuts and not for actual installation stuff. This is almost as bad as itch putting exe in data folder.
You should consider c:/games as a folder
Normal would be c:/progam files/, but that is restricted folder, so another folder is prudent.
