1. Rename the .dll file to xfire21.dll (for some reason that's the only way it works)
2. Inject like any other hack.

1. Launch Warrock
2. Press Ok
3. Press Ok again, and launch the hack (admin doesn't matter)
1. Launch the hack
2. Launch Warrock like normal

I don't know if it works for 32-bit OS's, but feel free to try. Also, ignore where it says "press End" on the injector. I used a no menu hack but I'm almost certain menu hacks will always be insert.
