RPCS3 Forums

Hello, today when I started my computer and tried to open RPCS3 it said "Fatal Error" and it read another instance of RPCS3 is open, please close or kill it's process. But when I went into Task Manager there was NOTHING opened from RPCS3, and I even restarted my PC, open as an Admin and Nothing!

If that error appears then you have rpcs3.exe running for sure

Run
taskkill /f /im rpcs3.exe
on cmd

If you get that while opening for the first time after a fresh boot, your graphics drivers installation is likely broken, use DDU and fully reinstall your drivers.
