ECommerce Starter Kit question (how make a 2nd site)?

[VB Programmer]

I installed IBuySpy ECommerce app and customized an ecommerce site.

Now I want to make a 2nd ECommerce app, based on the Starter Kit. But, when
I run Setup it asks if I want to repair or uninstall the current one.

How do I create a 2nd ECommerce site based on this Starter Kit? (Including
auto db setup, etc...)

Thanks!
