Need more details... Why are you trying to update to BIOS A06 now? This version is the latest but it's already 9 years old (released Nov 2011) How are you running the update? Inside Windows or from a bootable USB stick? If inside Windows, are you logged into an account with administrator privileges? If inside Windows, did you temporarily disable your anti-viral/anti-malware apps before launching the update?
When I run the downloaded file it seems to start but then I get the message "Fail To Launch Program, Process Aborted!".   I can't find a solution.  Any help would be appreciated, thanks!
