To perform a clean boot on Windows 7:
Click Start, type msconfig.exe in the Start Search box, and then press Enter to start the System Configuration utility. On the General tab, click the Selective startup option, and then click to clear the Load startup items check box. On the Services tab, click to select the Hide all Microsoft services check box, and then click Disable all.

Also makes sure your anti-virus/firewall has an exception for Final Fantasy XIV and that you are using a wired connection with an Ethernet cable.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
After following your instructions, the launcher stopped launching fully.
