Greetings,
It's possible the file you downloaded is corrupt.
I'd delete the old file and download a fresh copy. They try unpacking it.
If that fails, you can right-click on the file and change the extension from .exe to .zip. Then extract that. Note, you need to have display file extensions enabled in your view settings to see the extension for renaming.
