Unable to find drivers bios update error

I use an Inspiron 5680 desktop and have been postponing updating the bios for years as of the risks but since I'm getting a new pc next year I thought now might be the right time to update so I've been trying to install 2.0.7 the next one after min but it gave the error "unable to load driver" no matter what I've disconnected my antivirus and internet but still nothing and I don't use bit locker could anyone help me?
