I use Windows, and every time I try to use the new Minecraft launcher, I get this message:
Launcher started...
Getting syncinfo for selected version

Couldn't unpack natives!
java.io.FileNotFoundException: C:\Users\BenJ\AppData\Roaming\.minecraft\versions\13w16a\13w16a-natives\OpenAL32.dll (Access is denied)

This happens to me too, but the first time I tried to download it was actually downloading, but it had the message at the end and wouldn't work after that.
