Dell bios update exe was not able to read your current bios for whatever reason. flashing bios has inherent risk even with Dell recommended update (often labelled "urgent").  unless there is strong real urgent reason for your pc, think twice before taking a risk for nominal benefit of update that you may not need.  
I am attempting to update my R9 BIOS but have encountered the following. I have BIOS V: 1.0.14 however, I am receiving a NOTICE: "Running on an unsupported system." [IMAGE]   Please Advise.   Thank You.
