[Setup]: PrivilegesRequired

Valid values:

admin, or lowest

Default value:

admin
Description:

The effect of this directive depends on which version of Windows the user is running:

On Windows Vista and later:

This directive affects whether elevated rights are requested (via a User Account Control dialog) when the installation is started.

When set to admin (the default), Setup will always run with administrative privileges and in administrative install mode. If Setup was started by an unprivileged user, Windows will ask for the password to an account that has administrative privileges, and Setup will then run under that account.

When set to lowest, Setup will not request to be run with administrative privileges even if it was started by a member of the Administrators group and will always run in non administrative install mode. Do not use this setting unless you are sure your installation will run successfully on unprivileged accounts.

On earlier versions of Windows:

This directive specifies the minimum user privileges required to run the installation.

When set to admin (the default), Setup will only run if the user is a member of the Administrators group and will always run in administrative install mode. Otherwise, it will display the following message and exit: "You must be logged in as an administrator when installing this program."

When set to lowest Setup will not check the user's group membership and will always run in non administrative install mode. Do not use this setting unless you are sure your installation will run successfully on unprivileged accounts.
