Why does Windows Movie Maker 1 start on a machine on which I've installed Windows Movie Maker 2?

A. If version 1 starts after you install Windows Movie Maker 2, perform the following steps:

1. Start Windows Explorer.
2. Navigate to the \%systemroot%\RegisteredPackages\\{60BFF50D-FB2C-4498-A577-C9548C390BB9\} folder (where %systemroot% is the root of your Windows installation). The folder contains three files.
3. Copy the three files to the \%programfiles%\movie maker folder (where %programfiles% is your Program Files folder).
4. Click Yes to overwrite the files.
5. Navigate to the \%programfiles%\movie maker folder.
6. Right-click mm20ex.inf, then select Install from the context menu.
7. Run moviemk.exe to start Windows Movie Maker 2.
