I had to delete movie maker 2.1 from my system because it was functioning
improperly, however, when I try to remove the .dll files from the movie maker
folder, they come right back, and if I remove the folder in safe mode, it
also comes right back. I need to delete these files in order to use the
installer, because with the .dll files present, the installer thinks movie
maker is already installed on my computer, when it in fact is not. Does
anybody know a good solution to get rid of the dll files or the folder
entirely (maybe through the registry?)

Any help is greatly appreciated, I'm trying to make a movie for my
girlfriend, and this is not helping my project at all. Thanks in advance!
