Non Administrative Install Mode

An installation can run in one of two modes: administrative or non administrative. Which mode is selected is specified by the PrivilegesRequired and PrivilegesRequiredOverridesAllowed [Setup] section directives.

In administrative install mode:

In non administrative install mode:

Notes:

Regardless of the version of Windows, if the installation is running in administrative install mode then you should be careful about making any per-user area changes: such changes may not achieve what you are intending. The compiler will warn you about this, which can be disabled using UsedUserAreasWarning.

If the installation is running in non administrative install mode, but administrative privileges are available anyway then Setup or the [Code] section might still make use of these privileges. For this reason the uninstaller will always be marked as requiring administrative privileges in this case, just as if the installation was running in administrative install mode.
