This section contains global settings used by the installer and uninstaller. Certain directives are required for any installation you create. Here is an example of a [Setup] section:
[Setup]
AppName=My Program
AppVerName=My Program version 1.4
DefaultDirName={pf}\My Program
DefaultGroupName=My Program
By default, any leading or trailing whitespace in a directive's value will be stripped. It is possible to avoid this by surrounding the directive's value in double quotes (").
The following directives can be placed in the [Setup] section:
(bold = required)
Functional: These directives affect the operation of the Setup program, or are saved and used later by the uninstaller.
Cosmetic: These directives only affect the appearance of the Setup program.
These directives are obsolete and should not be used in any new scripts.
