Note that this solution is created for the 2.9.46.2 Build.
Using this method on future builds might work, but it will most likely try to download newer/more files from SOE servers.
Downloading the launcher
http://torrents.thepiratebay.se/7094124/PotBS_2.9.46.2_Launcher_Files.7094124.TPB.torrent
This torrent contains the entire launcher and will download into a folder called "Pirates of the Burning Sea"
Downloading the game's "PIG" files
http://torrents.thepiratebay.se/7072552/PotBS_2.9.46.2_PIG_Files.7072552.TPB.torrent
This torrent contains the game's "PIG" files and will download into a folder called "piggs"
Move files and folders
Now when the torrents have finished downloading.
Move the "Pirates of the Burning Sea" folder (and contents) that you downloaded to any location you wish, this location will be your game directory.
Now place the "piggs" folder that you also downloaded into your "Pirates of the Burning Sea" directory.
The result should be like this.
Example structure:
C:\Program Files\PotBS Alternative Install\Pirates of the Burning Sea
C:\Program Files\PotBS Alternative Install\Pirates of the Burning Sea\piggs
Running/Validating
Run "LaunchPad.exe"
The launcher should now check/validate all existing files
No further downloads should be required
Congratulations
You should now have the game fully installed and playable.
