Fix vJoy install failures, driver errors and detection problems.
Conflicting vJoy Installs: Remove Every Old Version Cleanly Many stubborn vJoy problems are not one broken install. They are several installs at war: an original-line build from one year, a fork from another, and the remains of a failed attempt, all sharing one driver name.
