I'm wondering if, perhaps, there isn't more to the install under Vista.
I'm getting 404 errors for /store/cart.aspx, /login.aspx, /register.aspx... basically any page but the home page. I installed the most recent copy from CodePlex. Any thoughts?
It's probably the UrlRewriter HttpModule that doesn't work in Vista. Try running it under Classic .NET App pool to see if it helps.
Awesome! That solved the problem. Thanks so much for the tip... Now I can start playing with this...
