Windows 7 - Unable to install hot fix for my onboard realtek sound

i jumped from Win XP to Windows 7 but the problem now is i have no sound device installeed on the taskbar i tried to install my original driver but i have install a Kb888III.exe hot fix to install my driver properly but the installer says 'u require a minimum of windows XP sp2 to apply this fix' i tried trouble shooting compatability but no use .........
Pls help me out

Go here and download the latest Windows 7 Realtek driver and install -
download from Guru3D.com

Hope this works - I'll check back - forget whatever driver your trying to use - i'll get your driver page and check to see what's availabe there. Hmmn just been there and there is a realtek driver version 5.10.0.5128 - is that what you were trying to install? See if you can get the above driver to install firstly and post back.
