Download Specific Version of Unity 3D

Hi friends!
I need to download Unity 4.1.3f3 but I can’t find it anywhere…
Even in this link, there isn’t that version to download:

There is only the version 4.1.3, but i need the 4.1.3f3, that have some 20 mb more than the other version.

Thank you!

f3 indicates release candidate. If that was the latest release candidate (i.e the one that got released), then it will be the same as 4.1.3 in the archive.
