title: "Launcher (ffxivlauncher.exe)"

{{< note "This documentation is incomplete." >}}
|
|
|
|
This is the program that logins into the official servers and launches the game.

# History
|
|
|
|
Since FFXIV has been around for a long time, it's went through several launcher redesigns.
|
|
|
|
## 1.x
|
|
|
|
This is the old launcher designed used for 1.x versions, before A Realm Reborn. This is [a recreation by Ioncannon](http://ffxivclassic.fragmenterworks.com/), as I can't find a screenshot of the original login page anywhere online.
|
|
|
|
|
|
|
|
## 2.x
|
|
|
|
The old launcher has been there since launch, but was on the path to be retired since the new launcher design was used.
|
|
|
|
|
|
|
|
## 6.5+
|
|
|
|
It seems as of Patch 6.5, the old launcher can no longer be used and all users must use the new design.
|
|
|
|
|
|
|
|
# Internals
|
|
|
|
The launcher is actually a website, and the launcher is served by the [Frontier server]({{< ref "/server/frontier" >}}) on URLs such as https://frontier.ffxiv.com/version_4_0_win/index.html?1559390056785.
|
|
|
|
In order for the launcher to actually launch anything useful, it uses JavaScript callbacks into native code.
|
|
|
|
For details on how logging into the Square Enix servers work, see the [relevant page on this concept]({{< ref "/concept/logging-in-official" >}}).

# Arguments
|
|
|
|
{{< note "Like the other executables, it requires you to pass these using the [SqexArg](concept/sqexarg) format." >}}
|
|
|
|
- `ExecuteArg` (**Required**)
|
|
- This is a strange argument. This appears to be a random gibberish of numbers:
|
|
|
|
`/T =1000000 /ExecuteArg =14431503 /UserPath =C:/users/yourname/Documents/My Games/FINAL FANTASY XIV - A Realm Reborn`
|
|
|
|
In reality, decompiling the launcher reveals that they are sprintf'ing in this format:
|
|
|
|
`%02d%02d%02d%02d`
|
|
|
|
- 1st arg - current month + 1
|
|
- 2nd arg - current day
|
|
- 3rd arg - current hour
|
|
- 4th arg - current minute
|
|
|
|
- `UserPath`
|
|
- Your usual path to your FFXIV data folder in `My Documents`.
