Unfortunately I don't have any experience of W7 but I am using CIS on Vista Ultimate x64 and it's faultless. Comodo's website actually isn't that easy to navigate for the right download. I know of several people who ended up with the x32 bit version when they thought they were getting the x64. Apart from that maybe there's some admin mode with W7 which you need to engage? I'm sure one of the other editors here with W7 knowledge will post soon with some advice.
