Ok, probably I can answer my own question now.
The reason why the custom action cannot be fired is due to the wixlib being
used to author our x86 components and the wixlib is referenced, together with
other x64 ones, to build final x64 MSI. The customactionref was added into the
wixlib part but seems this extra hierarchy prevented it from being fired during
patch install. It is strange though, no problem to fire it if the upgrade MSI
is installed. Neither the ORCA can tell any difference when customactionref is
inside wixlib part vs outside - probably never meant to be for those
pre-compilation info.

Btw, forgot to mention, I checked the patch install log, there is no any
indication on the new custom action is called or not. Searching new custom
action name in the log returned no hits.

Subject: [WiX-devs] cannot launch custom action during patch install
Hello Wix Devs,
I have a question for the problem I am currently working on with launching a
new custom action during a patch install:
Basically I need to launch an EXE file while is installed by the original MSI
during the patch/MSP install. The original MSI does not include this custom
action so I authored it in the upgrade MSI (add the customaction definition as
well as the installexecutesequence). Also in order to have it included in the
patch, I add the customeactionref to this new added custom action into the
patchfamily. The customaction definition and installexecutesequence are defined
inside the same fragment so both get picked up by the MSP.
Now, I can see both customaction definition and installexecutesequence are
shown up with the patch (using ORCA to load original MSI then view patch MSP).
Everything looks correct except when patch is installed, the EXE is not
launched. I have played with the condition for installexecutesequence even
tried remove any condition - meaning should launch it unconditionally. Still no
luck.
When I tried installing the upgrade MSI, the EXE is launched as expected. So
just cannot have it work with patch install.
Any suggestions?
Thanks
Hao
