This dialog asks whether IIS should be automatically configured by the LANSA install.
IIS needs to be configured if LANSA Web Server Extension, Web Images, Java Server Manager or Java Service Manager Proxy are being installed.
If you select Yes, IIS is stopped to be automatically configured. Once configuration is complete, IIS will be restarted.
If you select No, the files will be installed but you will need to configure IIS manually.
No is the default.
