I'm not at my home PC, so I'm not sure of the exact location, but...
If your download hasn't even started yet, you may want to try clearing the download cache for the entire client. Patch files are stored (by default) in your C:\User\<username>\Documents\My Games\FINAL FANTASY XIV - A Realm Reborn\<download folder>
It could be that the file was corrupted.
I forget the exact name of <download folder>. It is something obvious though, like downloads, or client patches. Just delete everything in THAT folder, then restart the client. It will start downloading the most recent patch from fresh.
