Write Address Violation

I keep getting an error message that says " Access violation at address 00409942. Write of address 00400000. " when I try to download Weather Watcher Live. Then nothing happens. What do I do?

Please give us more information about what you’re doing when you download Weather Watcher Live. It would be helpful if you could share detailed steps on how you’re able to reproduce this issue.

I found that shutting off my firewall and giving wwexe. permission in my firewall cleared up all problems.
