Chapter 12: Customizing Installations Using TunerValidation1008 ADS-0950-UG00 AdminStudio 9.5 User GuideUsing Response TransformsThere are two ways you can create a transform file in Tuner:• The first and the most common way is to begin by creating an empty transform and then makingcustomization by navigating to different views in Tuner.• The second way is by running the installation and then customizing various options available in each setuppanel. The installation is only simulated and no changes take place on the user system. Tuner saves all thechanges that the user has made on each panel of the setup in the transform. This type of transform is called aresponse transform.Response transforms, much like installation response files, allow you to run an existing Windows Installer-basedinstallation and capture your configurations. Unlike a response file, these changes are used as a starting point foryour new transform.For example, if you use Tuner to create a response transform, you might select certain features you want installed,the location of the installation, and company information. When the Tuner interface is opened, these values willalready be set for your new transform file. You can then make further customizations as necessary.You might want to create a response transform for an installation, and then fill in your company name as the defaultname, and a specific directory for installation which is different from the one suggested by the manufacturer.Further, you may want to configure a specific feature, such as clip art, to not be installed. By using the familiarinstallation user interface, you can quickly make your basic customizations before using the Tuner environment torefine the transform.Viewing Transform PropertiesTo view properties of the transform you are currently creating or editing, select Properties from the File menu. Toview the properties of a project from the Open a Recent Transform View, select the transform file and clickProperties or selecting Properties from the context menu.The resulting Properties dialog box provides information about the transform, including the name and location ofthe base Windows Installer file, and any additional transforms that are associated with this transform and MSI file.ValidationWhat is Validation?Validation is the process of comparing a Windows Installer-based installation to a known set of guidelines (anevaluation file) to ensure it has been created to those guidelines. Tuner can perform two types of validations:prevalidation and postvalidation.• Prevalidation compares only the base Windows Installer package to an evaluation file. This ensures that,when starting a customization project, the initial file was created using the guidelines in that evaluation file. If itdoes not pass prevalidation, then the installation may work fine, but it may not be able to use all WindowsInstaller features.
