Hello.
After you finish the Web Installer wizard successfully, you open a web browser and Database Setup wizard should appear. If it does not - what exactly do you see if try to open your site? Do you see some error message? What is says?
Did you install your Kentico
CMS on IIS server, or Visual studio build-in web server?
If IIS, could you please try use Visual studio build-in web server instead to determine, if this issue is related to your IIS configuration, or not? Thank you.
Best Regards,
