if i write the url url/default.aspx this redirect me to Install.aspx

im tryin' to install nopcommerce manually im already added the connection string but i dont know why if i write the url url/default.aspx this redirect me to Install.aspx.
someone knows about that?

thank you very much.

You can install nopCommerce using Installation Wizard, or manually (for advanced users). If it redirects you to install.aspx, then you havn't set your connection string.

P.S. If you're not sure how to insert connection string, then you can install nopCommerce using Installation Wizard and look at your web.config to see what changes are made
