The Fiori launchpad URL needs to be accessed in a web browser like Google Chrome, Mozilla Firefox etc. There is nothing that you need to/can install in a Windows system to access the launchpad. So assuming that you have done all the necessary configurations/activations for the Fiori launchpad you should simply be able to access it usng a web browser.
Regarding configuring SSO between Windows AD and Fiori you can refer to this document - Single Sign-On with Kerberos
