What's the problem exactly? I just tried the download and it worked for me. I know you have to have a bit of extra memory when installing any android app, so if it starts installing and then stops, it could be that you need more free memory.
If you can't open the APK file on your phone, you can try an APK file installer app from the Play Store. The one I use is called APK Installer by Braveheart.
