UnknownBuddy failed to get process handle

So i purchased unknownbuddy today to find that after i enter my serial i get the error message 'Failed to get process handle'
i have also disabled my antivirus.

 

Thanks for the response, I'm running windows 10 16299.98 and no I've definitely disabled everything, I'm trying to workout what process handle it's trying to grab before I even start the game.

 

Yes I am having this same problem is killswitch active this is my first time trying I have all my anti virus and windows 10 defender disabled

 

Yeah I do

 

Pretty sure it says not to run the game until unknown buddy is working
