How to Fix Roblox Error 403

Quick Fix

  • Press *Windows + R* keys and type %appdata% first and again *Windows + R* with %localappdata% inside the windows that open.
  • Look for the *Roblox* folder inside both of the File Explorer windows that opened, click it and press *Delete*. If only one of the windows features the Roblox folder that is fine.
  • Reinstall the game after this and it should work fine.

Another thing is that Roblox doesn’t like overlays on your screen so if you have the RivaTuner from MSI Afterburner overclocking utility running, try to turn it off and close the window to see if Roblox continues to throw the 403 error.
