Using the Custom Action Location Tab

The Location tab appears for custom actions only if you are working in the All Custom

Actions installation mode. The All Custom Actions installation mode lists all the

custom actions that are part of this installation, which are stored in the CustomAction

table. Also see All Custom Actions on page 489.

Note

The Location tab is an alternate way to perform tasks that you normally perform in the User

Interface, Execute Immediate, or Execute Deferred sequences. You can move and copy

custom actions by using editing functions in these sequences. The main use for this tab is to

click the No Sequence option, which causes this action to not run unless an event invokes it.

! No Sequence

Omits the custom action from all sequences, and stores it in the CustomAction table.

If you mark this, the custom action is only invoked if you set an event to run the

custom action. See Launching a Custom Action from a Dialog on page 504.

If you clear No Sequence, enter the following information:

! Sequence

Select a sequence to which to add this custom action. The options here correspond to

the sequences available with each of the 3 installation modes.

! Location list box

This displays all the custom actions that are part of this installation. Click on an

action in the list box and click one of the following buttons:

• Click Add to add the custom action to the sequence below the action you

selected.

• Click Remove to remove it from the sequence.

• Click Move Up and Move Down to specify where in the sequence the custom

action is stored.

! Condition

For this action to run only if a certain condition is true, enter a condition. In the User

Interface, Execute Immediate, and Execute Deferred sequences, the condition you

enter is displayed as an If Statement preceding the custom action. To use the

Condition Builder to create a syntactically correct Windows Installer condition, click

Build. See Creating Conditions With Condition Builder on page 409.
