AdminExecuteSequence Table
The AdminExecuteSequence table lists actions that the installer calls in sequence when the top-level ADMIN action is executed.
ADMIN actions in the install sequence, up to the InstallValidate action and any exit dialog boxes, are located in the AdminUISequence table.
ADMIN actions from the InstallValidate action through the end of the install sequence are in the AdminExecuteSequence table. Because the AdminExecuteSequence table needs to stand alone, it also contains any necessary initialization actions such as LaunchConditions, CostInitialize, FileCost, and CostFinalize.
Custom actions requiring a user interface should use MsiProcessMessage instead of authored dialog boxes created using the Dialog table.
The columns are identical to those of the InstallExecuteSequence table. The AdminExecuteSequence table has the following columns.
| Column | Type | Key | Nullable |
|---|---|---|---|
| Action | Identifier | Y | N |
| Condition | Condition | N | Y |
| Sequence | Integer | N | Y |
Columns
-
Action
-
Name of the action to execute. This is either a standard action or a custom action listed in the CustomAction table.
Primary table key.
-
Condition
-
Logical expression. If the expression evaluates to false, the action is skipped. If the expression syntax is invalid, the sequence terminates, returning iesBadActionData. For information on the syntax of conditional statements see Conditional Statement Syntax.
-
Sequence
-
A positive value indicates the sequence position of the action. The following negative values indicate that the action is called if the installer returns the termination flag. Each termination flag (negative value) can be used with no more than one action. Multiple actions can have termination flags, but they must be different flags. Termination flags (negative values) are typically used with Dialog Boxes.
Termination flag Value Description msiDoActionStatusSuccess -1 Successful completion. Used with Exit dialog boxes. msiDoActionStatusUserExit -2 User terminates install. Used with UserExit dialog boxes. msiDoActionStatusFailure -3 Fatal exit terminates. Used with a FatalError dialog boxes. msiDoActionStatusSuspend -4 Install is suspended. Zero, all other negative numbers, or a null value indicate that the action is never called.
