If not, head to the troubleshooting section down below! If it is, you can continue on to the game. If it does, check the console to say that LSPD First Response is running. To test if your LSPDFR works, start spamming F4 (I say spam, because it doesn't initialize right away) until a console pops up.
Finally! You've gone through and installed all the required things for LSPDFR! Time to play!
