I am trying since 2 days. I was able to Install but I Cant see my all services in 'SQL Server Configuration Manager and I cannot access sql server management studio. It works fine on my windows 7 laptop and it have all the services. Xp have only 'SQL Server(SQLEXPRESS)' running and 'SQL SERVER AGENT(SQLEXPRESS)' and 'SQL SERVER Browser' stopped. I right clicked and tried to start but start is disabled. I am not sure whether this is installation issue or because of windows xp.
You can find a list of supported operating systems and requirments here.
I checked for you and XP Professional service pack 3 is in the list.
You can try if updating your service pack works?
