Below is a list of all the wizard pages Setup may potentially display, and the conditions under which they are displayed.

• Welcome Shown by default, but can be disabled via DisableWelcomePage.
• License Agreement
  Shown if LicenseFile is set. Users may proceed to the next page only if the option "I accept the agreement" is selected.
• Password
  Shown if Password is set. Users may proceed to the next page only after entering the correct password.
• Information
  Shown if InfoBeforeFile is set.
• User Information
  Shown if UserInfoPage is set to yes.
• Select Destination Location
  Shown by default, but can be disabled via DisableDirPage.
• Select Components
  Shown if there are any [Components] entries.
• Select Start Menu Folder
  Shown if there are any [Icons] entries, but can be disabled via DisableProgramGroupPage.
• Select Tasks
  Shown if there are any [Tasks] entries, unless the [Tasks] entries are all tied to components that were not selected on the Select Components page.
• Ready to Install
  Shown by default, but can be disabled via DisableReadyPage.
• Preparing to Install
  Normally, Setup will never stop or pause on this page. The only time it will is if Setup determines it can't continue or if it detects applications using files that need to be updated.
  
  The former can happen if the PrepareToInstall event function returned an error or if one or more files specified in the [Files] and [InstallDelete] sections were queued (by some other installation) to be replaced or deleted on the next restart. In this case, it tells the user they need to restart their computer and then run Setup again. Note that this check is performed on silent installations too, but any messages are displayed in a message box instead of inside a wizard page.
  
  The latter can happen if CloseApplications is set to yes.
• Installing
  Shown during the actual installation process.
• Information
  Shown if InfoAfterFile is set.
• Setup Completed
  Shown by default, but can be disabled in some cases via DisableFinishedPage.
