Not sure if I am posting this correctly, so bear with me. (If this is not the correct forum, please let me know!) I have an SP2. Bought my friend a refurbished RT, with 8.1 installed. My friend purchased an aftermarket machine with software installation on a CD, to attempt to use with his RT. I think its only useful with 2000, XP, Vista. Can he run that software on his RT? If not, is it possible? I'm not a hardware guy; just a MS fan with love for my SP2; as well as his RT. (His RT works quite well; may I say!) What are his options?
