Scheduling Options
If you add the custom action to both the UI Sequence and the Execute Sequence, but
you want to limit the number of times it actually runs, select an option here. See Custom
Action Execution Scheduling Options in the Windows Installer SDK Help.
! Always Execute
Select this to have the action execute in all sequences that you added it to.
! Run first time
Select this to have the custom action execute only the first time Windows Installer
encounters it.
! 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.
! 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.
