If you have Microsoft Windows XP Home Edition installed on your computer, when you try to also install Microsoft Windows XP Professional Edition, you are not prompted for the location where you want the Windows XP Professional files installed. Setup installs the operating system in the Windows folder where Windows XP Home Edition is installed. This behavior also occurs if you have Windows XP Professional Edition installed on your computer and then you install Windows XP Home Edition.
