I have SCAl 1 and bought it for my desktop which runs windows Vista. I now have a laptop and would like to install SCAL on it, I know I am allowed 2 computers, my laptop runs Windows 7. My question is can I still install it on the laptop running 7? The back of the box does not list 7 only up to Vista.

I have windows 7 and I was told to right click the scal icon and go under properties and in compatibility check off windows xp service pack 2. This has worked well for me, once in a while if I have a problem I right click the Icon and run as the admin.
