[Bug 34989] Multiple installers using Caphyon 'Advanced Installer' (AI) technology hang (Atlassian SourceTree v1.3.2, League of Legends 2013+) (deferred type 1 custom action executed before regular type 1 custom action)

--- Comment #15 from Sebastian Lackner <sebastian at fds-team.de> ---
The information on the following website
http://www.installsite.org/pages/en/isnews/200108/ seems to confirm my theory:

"""While the installer builds the script, only immediate execution custom
actions are actually executed. All other actions (standard actions like
InstallFiles and deferred execution custom actions) are only noted in the
script."""

"""All the script execution takes place "inside" the InstallFinalize action."""

By the way ... Rollback execution is also implemented completely wrong:

"""While the installer executes the installation script, it builds a rollback
script. For any standard action in the installation script, a rollback command
is added to the rollback script. The installer cannot automatically undo
changes that custom actions make to the target system. Instead it adds any
rollback custom actions to the rollback script."""

With the current method (build the rollback script directly in phase 1) this
obviously can't work correctly. The rollback script has to be generated while
processing the install script, to make sure only failed parts are actually
rolled back and not everything. Wondering a bit why the current implementation
works at all ;)
