You can use the full installer just as if it was the patch. There's no *need* to uninstall, just do it if you have any problems.
And no, Mediafire is not "unreliable". If we had to host files on our servers, it will become way more unreliable than Mediafire, since we don't obviously have a separate server for each file, like they have, and we don't have basically unlimited bandwidth, like they have.
EDIT:
If you refresh your browser, it should work now, because we uploaded it again so, it was moved to a different server.
