Introduction
You can use the Microsoft® Web Platform Installer (Web PI) to easily install Internet Information Services (IIS), and applications that run on IIS. To learn more about the Web PI, see Learn about and install the Web PI.
If you choose to install IIS 7.0 or IIS 7.5 (collectively known as IIS 7) manually, you can use this article for guidance.
Before You Begin
Ensure that you have installed one of the editions of Windows Vista or Windows 7 on which IIS 7 is supported before you proceed. Not all IIS features are supported on all editions of Windows Vista and Windows 7. Home Basic and Starter editions include only limited basic features of IIS. To see a list of which features are supported on the edition of Windows you are using, see one of the following:
Available Role Services in IIS 7.0 (Windows Vista)
Available Web Server (IIS) Role Services in IIS 7.5 (Windows 7)
Also be sure that you have administrative user rights on the computer. By default, you do not have administrative privileges if you are logged on as a user other than the built-in administrator, even if you were added to the local Administrators group on the computer (this is a new security feature in Windows Server® 2008 called Local User Administrator). Log on either to the built-in administrator account, or explicitly invoke applications as the built-in administrator using the runas command-line tool.
Note that you can run runas /user:administrator cmd.exe so that every application you run from that command line will be elevated, eliminating the need to use the runas syntax from that command line.
If you are logged on to an account other than the built-in local administrator account, you may see the following security alert dialog box.
