When installing McAfee make sure all previous entries in Control Panel > Programs > Uninstall a Programs pertaining to McAfee are uninstalled. (Add or Remove Programs in XP)
Do the same for any previous antivirus and run their removal tool.
Run McAfee's removal tool (MCPR) which is linked under Useful Links at the top of this page or here: http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe
Run the McAfee Preinstall tool: http://download.mcafee.com/products/licensed/cust_support_patches/McPreInstall.e xe
Install your software from your online account, https://home.mcafee.com/secure/protected/login.aspx?
Unless you don't yet have an account in which case use the CD.
