Alienware M17 R1 BIOS UPDATE Alienware_m15_m17_2.17.0.exe

I have regularly updated the Bios using the "forceit" method as described on Dell`s website. There are also vids on You Tube detailing various ways to do it.

I have never had a problem updating the BIOS but the recent update Alienware_m15_m17_2.17.0.exe will not work via cmd or run method. Worryingly. I get a message "Error: Secure flash check failure (0x1)"

I note there is a method using Rufus but this looks a tad complex for me. 

Any suggestions as I am reading that the error suggests that this is not the correct file but this is what is available on the DELL update site.

The current BIOS is 2.16.0

thank you
