Download a patch release from the Announcements thread:

http://forum.unity3d.com/threads/unity-patch-releases.246198/

These patches are presented with a file size and MD5 hash, so you can quickly check whether your download is corrupted or not.

The installer should verify its integrity using a bundled MD5 as the first step of the install process.

Likely this means some other process is interfering with the install. To get around this I restarted my machine and closed all other running processes.
