Custom Action Reference
z
Run once per process
Select this option to prevent the custom action from running twice if the custom
action modifies property or database data. Use for custom actions in either Execute
sequence that should not run if the installation is running in silent mode.
z
Run only if UI sequence was run
Select this option if the custom action should run only if either Execute sequence is
run following User Interface sequence.
Progress Bar Text
Enter the text to display with the progress bar while the action runs. The action must be
placed in the Execute Deferred sequence for the text to be displayed. You cannot enter
properties or other formatted text; see Formatted in the Windows Installer SDK Help.
The field length is limited to 64 characters and two lines.
Using the Custom Action Description Tab
The Description tab appears on the details dialog box for all custom actions.
The Windows Vista Logo Program requires you to document every custom action in an
installation. The Windows Vista Compatibility Checks validation module in Package
Validation includes a check for custom action descriptions. If you plan to certify an
installation for Windows Vista or later operating system, use the Description tab to
document custom actions.
This requirement applies to the Wise custom actions as well as the ones you add. For
information you can use to document Wise custom actions, see
Wise Custom Actions
on
page 502.
To obtain a report of each custom action and its description, select Reports menu >
Custom Actions.
