Runtime Properties
The properties listed in Build Properties on page 416 represent properties that are
initialized by the installation. All build properties are also runtime properties. Windows
Installer sets additional properties at runtime that contain useful information you can
use in an installation. For definitions of all properties Windows Installer sets at runtime,
see Property Reference in the Windows Installer SDK Help.
When you add Web resources to the Web Files page in Installation Expert, the following
properties are set by a custom action. These properties are provided so you can grant
the ASPNet account permission to directories; see Setting Permissions for Files and
Directories on page 136.
Remove Previous If this is set to 1, the end user is prompted to remove any previously installed
versions of the same application. It is set to 1 if you mark the Prompt to
remove previous version before installing checkbox on the Build Options
page. The message stored in the WiseInitExistError property displays.
Runtime9x Contains the relative pathname of the file that installs Windows Installer for
Windows 95/98. Do not change this property unless you change the location
of this file.
RuntimeNT Contains the relative pathname of the file that installs Windows Installer for
Windows NT, 2000, or XP. Do not change this property unless you change the
location of this file.
RuntimeVersion If an installation includes the Windows Installer runtime, this is the version of
the included Windows Installer. You set an installation to include the Windows
Installer runtime on the Prerequisites page.
SpaceError Contains the error text that is displayed if the destination computer does not
have enough free disk space to copy the .MSI database to its local disk drive.
This defaults to the value of the build property named WiseInitSpaceError. See
Build Properties on page 416.
TransformMSI The TransformMSI .INI value is used if the file referenced in the ProductFile
property is an .MST. In that case, the TransformMSI property contains the
relative pathname of the base .MSI for the .MST.
WiseInitLangDefault Contains the default installation language. This defaults to the value of the
build property named WiseInitLangDefault. See Build Properties on page 416.
WiseInitLangPrompt Text that displays on the dialog that prompts the end user for a language
during installation, which happens when you create a multiple-language
release. Defaults to the value of the WiseInitLangPrompt property in the
Property table.
WiseInitPrefix Text that displays before the “Wise Installation” text in the installation’s
initialization window. The initialization window is the small window that
appears before the installation wizard dialogs appear. This defaults to the
value in the build property WiseInitPrefix. See Build Properties on page 416.
WiseInitProgressText Enter the text that displays with the hourglass during installation.
WiseInitSuffix Text that displays after the “Wise Installation” text in the installations’s
initialization window. The initialization window is the small window that
appears before the installation wizard dialogs appear. This defaults to the
value in the build property WiseInitSuffix. See Build Properties on page 416.
