HOW TO Delete that Folder that windows Says Does not exist
First Open CMD as Admin
then type CD %USERPROFILE%\DESKTOP
Then Type DIR/A/X/P
this will open a directory of all the things on your desktop you may have to hit enter a couple times to expand the list if you have a lot of things on your desktop
search and find the folder name in the list, and look at the short version of the name it it will have a ~ in it.
example GUILDW~1 for Guildwars,ink
now in the next command type REN GUILDW~1 KILL ofcourse relacing with your folder name, KILL is just the name im using, it can be anything. this will rename the folder KILL or what ever, and you can now delete it :)
You can delete it with the command, but renaming it is safer, as that allows you a chance to make sure its the folder you wanted to delete, and not a closely named folder.
