Installation Sequence

This dialog is displayed at the end of an installation that was ended by the user.

This custom action extracts any files that you have added in the Support Files view. For more information, see Using Support Files.

This action can be used to identify and locate files on the target system. The Signature table that this action requires is available in the Direct Editor. Knowledge Base article Q103147 provides detailed information on using this action.

This dialog is displayed while the setup is preparing to begin. The default text for this dialog is "Preparing to install..."

The CCPSearch action allows you to check the end user’s system for products qualifying for upgrade. The Signature table that this action requires is available in the Direct Editor.

Use the Validate Product ID action to set the ProductID property to the complete product identifier. This validation allows you to protect your software from illegal use by requiring users to enter the product ID.

The FileCost action determines how much disk space is required by the current configuration of the installation. It checks to see if any files will be overwritten with later versions, and it calculates how overwriting those files affects disk space. To complete costing, you need to use the CostInitialize action in conjunction with the CostFinalize action.

This custom action initializes the USERPROFILE directory identifier.

This custom action initializes the ALLUSERSPROFILE directory identifier.

The Calculate Disk Space action determines the total amount of disk space required by the installation in its current configuration. This action also verifies that all target directories are writable. The actions Initialize Disk Space Calculations and Initialize Dynamic Disk Space Calculations must be called before the Calculate Disk Space action; otherwise, the action will fail.

This action is used during application upgrade. The feature states of the original installation are read from the target machine and applied to the upgraded features.

The InstallWelcome dialog displays your Welcome panel when an InstallScript MSI installation is run.

This dialog opens when the end user tries to change a program’s installed features, remove the program, reinstall the program, run an installation for the second time, or select the current product in Add or Remove Programs.

This action queries the EXECUTEACTION property to determine which top-level action should be called first, and then calls that top-level action. Top-level actions include the INSTALL, ADVERTISE, and ADMIN actions. Typically, this action starts the Installation Execute sequence.

The ISSetAllUsers custom action is inserted in the both the User Interface and Execute installation sequences only if one or more records are in the Upgrade table.

This action evaluates a set of conditions that must return True if the installation is to continue. If any condition fails, the installation displays an error message and the installation ends. You can edit launch conditions in the General Information view.

The CCPSearch action enables you to check the end user’s system for products qualifying for upgrade. The Signature table that this action requires is available in the Direct Editor.

Use the ValidateProductID action to set the ProductID property to the complete product identifier. Validation allows you to protect your software from illegal use by requiring end users to enter the product ID.

This action determines how much disk space will be required by the current installation configuration. This action checks to see if any files will be overwritten with newer versions and calculates how overwriting those files will affect disk space.

The CostFinalize action determines the total amount of disk space required by the current installation configuration. This action also verifies that all target directories are writable.

The SetODBCFolders action checks for existing ODBC drivers on the target system and sets the target directory of each new driver to the location of an existing driver.

The InstallValidate action determines if there is enough disk space available for the current installation configuration.

The InstallInitialize action signals the beginning of the actions that make changes to the end user’s system.

The ProcessComponents action is responsible for unregistering and registering components. This action also registers or unregisters a component’s key path and any other clients that the component has.

The MsiUnpublishAssemblies action handles uninstallation of the assembly with the operating system.

This action stops the Windows services that are configured to be stopped. For more information, see Installing, Controlling, and Configuring Windows Services.

This action unregisters COM+ applications.

During uninstallation, this action unregisters every file in the TypeLib table that is marked for uninstallation. This table is populated when you create a new TypeLib through the COM Registration advanced setting.

This action unregisters information about all the fonts that are set for uninstallation.

This action manages system registry information removal for COM classes that belong to features that are being uninstalled.

This action unregisters all of the ProgIDs created in the File Types advanced setting.

This action removes only the .ini information that has been associated with a component in the IniFile table—or using the INI File Changes view. After verifying the presence in the IniFile table, this action removes all .ini files that are listed in the RemoveIniFile table if the component with which those files are associated is marked for uninstallation and the component was installed locally or set to run from source. The RemoveIniValues action also removes all .ini files that were written with the WriteIniValues action if the components with which they are associated are marked to be uninstalled.

When a component is removed, this action reverses any changes made to environment variables by the WriteEnvironmentStrings action during installation or reinstallation. You can specify environment variable changes using the Environment Variables view.

This action removes files that were originally installed by the InstallFiles action, if those files were set to run from source or installed locally, and the component with which they are associated is marked for uninstallation.

This action creates empty folders for components that are set to be installed locally. These new folders are then registered with the associated component GUID (found in the component’s Component Code property).

The InstallFiles action copies all of the selected feature’s files to the target machine if the component feature to which those files belong is marked for installation. Only files that are associated with components that are to be installed locally are copied to the target machine.

The DuplicateFiles action creates copies of certain files installed with the InstallFiles action. These files can be copied to the same directory as the original and given a different name, or they can be copied to a separate directory while maintaining the original name. The DuplicateFiles table, used by this action, is available in the Direct Editor.

This action registers all of the MIME types that you defined in the File Types advanced setting that are linked to class servers or extension servers marked for installation.
