Custom action fails to create (& start) eclipse mosquitto broker service during Upgrade but works well on initial install and uninstall of the parent application

[OmSharmaDomino]

Hi,

Following is the code segment that I have for wix 4 installer

Product.wsx :

<Package ... >







:

: : :

EclipseMosquitto.wsx file :

:

 <CustomAction Id="StartMosquitto"
	Execute="immediate"
	Impersonate="no"
	Property="SCEXEFILE"
	ExeCommand="start  mosquitto" />

<CustomAction Id="StopMosquitto"
	Execute="immediate"
	Impersonate="no"
	Property="SCEXEFILE"
	ExeCommand="stop  mosquitto" />

<CustomAction Id="InstallMosquitto"
	Execute="immediate"
	Impersonate="no"
	FileRef="mosquitto_exe"
	ExeCommand="install" />

<CustomAction Id="UnInstallMosquitto"
	Execute="immediate"
	Impersonate="no"
	FileRef="mosquitto_exe"
	ExeCommand="uninstall" />

 <InstallExecuteSequence>
	 <Custom Action="InstallMosquitto" After="StartServices" Condition="(INSTALLECLIPSEMOSQUITTO=1) AND (NOT Installed)" />
	 <Custom Action="StartMosquitto" After="StartServices" Condition="(INSTALLECLIPSEMOSQUITTO=1) AND (NOT Installed)" />  
 </InstallExecuteSequence>

 <InstallExecuteSequence>
	 <Custom Action="StopMosquitto" Before="InstallInitialize" Condition="(INSTALLECLIPSEMOSQUITTO=1) AND (Installed) AND (REMOVE~=&quot;ALL&quot;)" />
	 <Custom Action="UnInstallMosquitto" Before="InstallInitialize" Condition="(INSTALLECLIPSEMOSQUITTO=1) AND (Installed) AND (REMOVE~=&quot;ALL&quot;)" /> 
 </InstallExecuteSequence>

: : : : : -------------------------------

Notes :

1. Running on windows 10 : x64
2. INSTALLECLIPSEMOSQUITTO property is set to 1 if the user ticks the checkbox in the UI
3. On installing, the eclipse mosquitto service gets created & started. Also the application is installed correctly
4. On uninstalling, the mosquitto service gets stopped and service deleted and the application uninstalls correctly

Problem :

To test the major upgrade
I increment the version number in the Package element in product.wsx and in the Bundle element in Bundle.wsx

The upgrade fails at StartMosquitto Custom Action
If I comment out the following line in the InstallExecuteSequence in the code and test it
<Custom Action="StartMosquitto" ..../>
Then the upgrade is successful

This meant Action="InstallMosquitto" is failing.
So after the successful upgrade I manually ran the following command to install the mosquitto service
mosquitto.exe install
and then to start the mosquitto service I run the following command
sc start mosquitto
and all works good ie the service get started abd ready to go.

But I dont want to manually create or start the service rather it should be
done from the Custom action

Any idea why are the InstallMosquitto and the StartMosquitto actions failing
What wrong am I doing?
