Questions
Short answers to what usually comes up.
Which one should I pick?
Installing for the first time: the Full Installer. Already have the mod from the original installer and want to keep it as is: the Stick Fix launcher. You don't need both.
The mod updated. Do I need to do anything?
If you use the Stick Fix launcher, no. It works on top of the original mod, so it should keep working after updates. Keep starting the game with it.
The sticks still don't respond.
Check that both controllers show up in SteamVR before you start the game, and that you started the game with the file from this page. If the mod updated and the sticks stopped working, download the newest file from this page again.
How do I check the file is the right one?
