Inno Setup is a free installer for Windows programs. First introduced in 1997, Inno Setup today rivals and even surpasses many commercial installers in feature set and stability.
Added new [Setup] section directive: UsePreviousLanguage. When
this directive is yes, the default, at startup Setup will look in
the registry to see if the same application is already installed, and if so,
it will use the language of the previous installation as the default
language selected in the list of available languages on the Select
Language dialog. Note that this directive does not change the language
used by the Select Language dialog itself because it cannot assume
that the current user understands the same languages as the previous user.
UsePreviousLanguage must be set to no when AppId
On Windows Vista and newer, Uninstall no longer blocks system shutdown
until the uninstallation has actually started. This should make the Windows
7 Logo Kit (which wrongly tests any .exe in the application directory
including the uninstaller) happy when it tries to shutdown an Uninstall
sitting on its confirmation prompt.
On Windows NT and newer, PrivilegesRequired=lowest now has an
additional effect: the uninstall info root key will always be
HKEY_CURRENT_USER, and the "common" forms of the Shell Folder constants are
always mapped to the "user" forms, even if administrative privileges are
[Setup] section directive CreateUninstallRegKey may now be set
to a boolean expression, which may contain calls to check functions. For
example: CreateUninstallRegKey=not IsTaskSelected('portablemode').
See the CreateUninstallRegKey documentation for details.
The Preparing to Install wizard page now offers the user an
option to directly reboot instead of just saying a reboot is needed. To
trigger this option from a PrepareToInstall event function set its
new NeedsRestart parameter to True.
In the MinVersion and OnlyBelowVersion directives and
parameters, .x is now treated the same as .0x when a major
version of 5 or higher is specified. Thus, you now have the option of using
either 5.01 or 5.1 to specify Windows XP. However, to
maintain compatibility with existing scripts, 4.x will still be
interpreted as 4.x0.
Pascal Scripting: Added new PageIndexFromID support function.
