Salaam All Experts,

I have a PC suite for my mobile phone, When i try to install it demand for Service pack 3. but i m using xp service pack 2.
I just convert service pack 2 to 3 by the method of changing in registry and successfull installed that program but mobile do not connect with that pc suite. (its mean it is not working)
but i intalled the same softwere in win 7, thats worked.

I wanna make my xp service pack 2 to 3 by downloading all files of service pak 3 not by registry. I think then it will work with my windows.

so plz help
