So the devs / admins don't like this but here is the links and instructions everyone's asking for.
First realize that the more recent Windower launcher was compiled with some sort of 64-bit library requirement, even though FFXI and all related components are 32-bit. This means you can't even load the windower launcher. So if your running any 32-bit version of Windows 7 or 8 then your fucked until they recompile.

After you copy and past those into your windower folder you need to go to windows firewall and create an output rule blocking access to IP 69.64.46.229 which is where windower downloads itself from.
Now you can start it up without it trying to update itself and breaking your play.
This is just a temporary solution until the developers roll back some of the changes they made.
