To help you detect and resolve potential problems in your installation project, you can perform several types of validation before you run the installation on a target system. The types of validation discussed in this white paper include:
• Build warnings and errors
• Internal Consistency Evaluator (ICE) validation
• Update and patch validation
Addressing these types of design-time validation errors will help
you avoid errors. This white paper also shows you how InstallShield® helps you with design-time validation.

The types of validation discussedin this white paper include: • The Release Wizard, available under the Build menu and also from the Releases view, lets you describe the properties— • Build warnings and errors media type, compression settings, and so forth—of a release, • Internal Consistency Evaluator (ICE) validation and then builds the specified release image. • Update and patch validation • The Component Wizard, available by right-clicking a feature in the Setup Design view, lets you create special types ofAddressing these types of design-time validation errors will help components, such as components for COM servers, fonts,you avoid errors.

The InstallShield Help Library contains information about usingUsing the InstallShield Environment every view and wizard in the InstallShield environment. TheThis white paper frequently refers to the InstallShield development InstallShield Help Library is available when you press F1 withenvironment. It is assumed you are familiar with the general layout any view selected; you can also select Contents from the Helpof the InstallShield interface, which contains a list of views with menu to view the help library.which you can modify different portions of your installation project. In addition to the graphical environment, InstallShield provides several tools for modifying and building projects from the command line or an external script. For example, to build a project from the command line, batch file, or other automated process, you can use the executable IsCmdBld.exe. The IsCmdBld executable is located in the System subdirectory of the InstallShield distribution directory. To rebuild a project, you pass IsCmdBld the project file path, the product configuration name, and the release name that you want to rebuild. A sample command appears as follows: iscmdbld -p C:ProductName.ism -a BuildConfig -r ReleaseName In addition, InstallShield provides an Automation interface, with which you can modify the contents of a project file without using the graphical environment.For example, the General Information view is where you set generalproduct and project properties; the Setup Design view enables you Learn More about InstallShieldto edit the features, components, and component data used by your If you wish to learn more about the capabilities ofproject; the Registry view enables you to modify the registry data InstallShield, please visit the Flexera Software Web siteinstalled by your installation program; and the Direct Editor view at www.flexerasoftware.com/installshieldgives you access to the raw MSI database tables.2 Flexera Software: InstallShield White Paper Series

WheneverAs InstallShield builds your project, status messages are displayed in you add a file to a component, InstallShield by default creates athe output window at the bottom of the development environment. path variable or reuses an existing path variable to represent that file’s location. If you move the source file, instead of having to reestablish the file link, you can simply assign the path variable a new value in the Path Variables view of the InstallShield environment. (The InstallShield help library also describes registry- based and environment variable–based path variables, with which you can modify path variable values without having toFor a command-line build using IsCmdBld.exe, status messages are modify the project file.)displayed at the command prompt.

An important consideration regarding file linking is that a dynamically linked file cannot be the key file of its component. However, a component can contain any combination of static and dynamic links, and therefore a solution is to set a statically linked file as the key file, additionally marking the key file as an exclusion to the dynamic link.Addressing Build Errors and WarningsBuild errors and warnings typically refer to missing or unexpected Moreover, when using dynamic file linking, it is important tosource files or merge modules, but can refer to any condition that specify a “previous package” in the build settings to ensure File,prevents a build from completing.

Using this setting ensures that certain types of dynamic data in the File, Component, and Media tables is compatible between builds. Some of the common upgrade and patch validation failures are: • Val004: Displays an error if a change to an existing component’s files will prevent the component from being updated in a minor upgrade. • Val006: Displays an error if a minor upgrade is being performed when a major upgrade should be; for example, because a component has been deleted or moved in the product tree. • Val008: Displays an error if a record in the Upgrade table for a major upgrade contains invalid data. By default, upgrade and patch validation is performed each time you build your project. You can also manually perform this type of validation by pulling down the Build menu, selecting Validate, and then selecting Upgrade Validation Wizard. When you test an update project from the InstallShield environment, by default clicking the Run toolbar button causes any version of the product already on the system to be uninstalled.
