Plutonium

Okay so what i did to solve this is: Make an exeption to the entire plutonium folder in C:\Users{NAME}\AppData\Local\Plutonium by your Antivirus. Specifically the one named "plutonium-bootstrapper-win32.exe" located in the bin folder, as this was the file that kept being deleted by my anitvirus and kept causing the launcher to crash whenever i clicked "Play".
Hope this helped!
