all the folders are in my desktop. and im not sure if its zipped or unzipped, but i tried clicking on another one that i found and it worked. it seems to be just my desktop shortcut as far as i can see.
(i know nothing about computers, bear with me
)
There are too many pronouns in that paragraph for me to follow properly.
Try downloading the .zip into C:\Downloads (make the directory if it doesn't exist yet)
Use file explorer to see the Downloads directory then right-click on the .zip file.
There should be some option to Extract all or something... click it.
You should now have a directory underneath Downloads like Mythruna-20120626-Windows or whatever.
In that directory is an .exe file. Double click it.
If that doesn't work then I will describe how to use the command line to find out more. But it's easier if I already know what the directories are.
