Hi - I have recently purchased a new laptop which is Windows 7. When I try to install SC2, I get a message saying: "Do you want to allow the following programme from an unknown publisher to make changes to this computer?"
What will happen if I say yes to this? Will it do something horrible and irreversible to my laptop or is it a harmless question. I guess my question is in what way does it want to change my computer?
Any help gratefully received
Regards
