Drivers won't install

Hello,

I have a problem with the drivers, I did upgrade and format my laptop Dell Latitude E6410 from Windows 7 to Windows 8 after that I downloaded the required drivers but some of them won't install, they gives me " You must upgrade to A11 before flashing to this BIOS" , "This package is not appropriate for this system" and "This computer does not meet the minimum requirements for installing the software" messages.

What can I do? someone said that I have to go back to Windows 7 then update it then upgrade it to 8! is there any other solution than this because I don't want to waist more time and I'm afraid it won't work either.
