Two steps are necessary to add this functionality to the install project:

1. Code the InstallScript function
2. Create the InstallScript Custom Action

Below are the detailed instructions for performing both these tasks:

Code the InstallScript function

1. Open the Install project in the InstallShield IDE under the "Installation Designer" tab.
2. In the left pane, go to the Behavior and Logic->InstallScript view.
3. In the middle pane, right click on the Files node and select "New Script File" from the popped up menu. This will add a setup.rul file to the project.
4. To edit the setup.rul file, click on the setup.rul node. The Script Editor should now be displaying the contents of setup.rul in the right pane.
5. Add the following line to the setup.rul file:

export prototype CheckForDirectory(HWND);

6. Add the following function to the end of the setup.rul file:

//Declare string variables

1. In the left pane, go to the Behavior and Logic->Custom Actions and Sequences view.
2. In the middle pane, right click on the node labeled "Custom Actions" and select "New InstallScript" from the popped up menu.
3. In the right pane, right click on the far right of the "Function Name" row, click on the down arrow control, and select"CheckForDirectory" from the drop down list.
4. Leave the "In-Script Execution" property set to the default, "Immediate Execution"
5. Leave the "Execution Scheduling" property set to the default, "Always Execute".
6. Using the row?s drop down arrow, set "Install Exec Sequence" to "After InstallValidate"
7. To prevent the Custom Action from running during uninstall, set the "Install Exec Condition" to REMOVE<>"ALL"
8. To prevent the Custom Action from also running during a silent installation, modify the condition to (REMOVE<>"ALL") AND (UILevel=5)
