If you've already created a fixlist and it's somewhere other than on your Desktop, then you need to drag and drop it onto your Desktop and then when you hit fix, FRST will be able to process it.
I know you have at least one copy of FRST.exe on your Desktop, since your log tells me that that's where the scan was run from, so it's just a matter of making sure you have a copy of fixlist on your Desktop as well.
Don't worry about any other copies of FRST you may have, we'll remove them all when we finish, though why you should have more than 2 is somewhat puzzling, since as far as I'm aware you've only downloaded 2 copies (you lost the first copy somehow).
