In ZCM 10.3.3 I want to use the file removal action to remove a temporary directory I have created after the install has finished. I have an app that does the following under the 'Actions | Install' tab:

1. Does an Install Files action to push down an installation file to a subdir of ${TempDir}
2. Launch Executable to run the installation file after it has been pushed down
3. File Removal action to remove the subdir.

How can I make the File Removal action wait until the installation has finished instead of running right after the executable has been launched?
