Hi Munish,
You need a valid license to install IS & Broker. If this is for a local install, please check with the organization you work for, for the licences. Also follow up with the keymaster, if he can provide you with a trial license.
Are you using any proxy in your network? If you are, then use the section “Use Proxy Server” under the “Servers” tab of the installer (Advance options) and state your proxy information there before starting the download.
Good luck,
SB.
