# Could not connect to driver

Fix issues relating to "could not connect to driver"

Because of how advanced Byfron has become, Horizon has been forced to enter the Kernel to maintain stability. This, of course, poses more issues than normal with the most popular issue being "Unable to connect to driver".

First, disable any third party anti viruses and anti cheats. **If you have Valorant or FaceIt installed, uninstall Valorant and FaceIt** (These are the correct terms - for Vanguard you must uninstall the entire game, and for FaceIt you just need to uninstall the Anti Cheat itself)

Next, restart your computer, Re-Download Horizon, and try again.

If you have followed **everything** in this guide and still get the error, make a ticket.
