if you have win xp x86 installed on your pc/laptop, you must perform a clean installation, even if you have a "upgrade cd"
Microsoft recomends the following upgrade path
Windows XP x86 to Windows 7 x64 the user must perform a clean installation
Windows Vista x86 to Windows 7 x86 upgrade is available and clean install is optional
Windows Vista x86 to Windows 7 x64 the user must perform a clean installation
if you have the "upgrade cd" , is possible that the installer request you the original media of the previous version
