Since January 10, 2017, Windows Movie Maker is no longer supported.
Microsoft had promised a new UWP version (universal app) but so far nothing has been published.
On Win 10 (64 bit) WMM (version 2012) not run and the version from this site not run.
What to do?
You can install Window Movie Maker 6.0.
Here all links:
Window Movie Maker 6.0 (64 bit)
Window Movie Maker 6.0 (32 bit)
Italian Language Package
(Open the downloaded compressed file, extract the contents (it will be the folder it-IT name) in Movie Maker.)
Full HD Export Package
(Open the downloaded compressed file, and extract the contents (it will be the folder named Profiles) inside the Shares folder.)
If you do not want to use WMM there are several alternate alternatives.
