What do you mean by "Download folder"? The folder you downloaded the game's installer to? If that's the case, I get those warnings too, on Windows 7. Even if it's not, this is probably still good advice: just restart. Sometimes I find Windows 7 will cling to a folder, sometimes even an empty folder, for no good reason for several hours, even. Sometimes it doesn't clear up at all. I have a sneaking suspicion Firefox might be responsible, but that's not important. Restarting should get the OS to let go, move on, start a new life in a new town, as tender but hopeful piano music swells.
