Capture NX2

--Hopefully the right forum

1) I'm not computer literate
2) recently installed Capture NX2, Win XP home, 2 gig memory.

3) Problem is every time I try to open a image it goes to CNX2 which I don't want.

How can I (make it simple) stop this action. I wnt to start NX2 when and if I want to.
Appreciate any help
Thanks.
