Error message when I try to run the downloader

[Lieutenant-Lettuce]

when I try to launch this to download it I get an error message saying that it failed to create steam_appid.txt and access to the path is denied and I have no idea why or how to fix it.

You probably copied/extracted AML to a folder that is write protected.

I made the folder on my desktop.
