Hello

I am using WIX 3.8 to generate an .msi file to install an app. The Wix file contains a custom action :

<CustomAction Id="LanceScripts" FileKey="LanceurScripts" ExeCommand="" Return="asyncNoWait" />
    <InstallExecuteSequence>
      <Custom Action="LanceScripts" After="InstallFinalize">NOT Installed</Custom>
    </InstallExecuteSequence>

1) when I start the installation by double-clicking the .msi file, the custom action is not executed !
2) when I start the installation with the msiexec utility (msiexec /i MyApplication.msi /l*v MyLogFile.txt), the custom action is correctly executed !!

Can someone please explain why and what should I do to execute by double-clicking ? Thanks
Thanks

Are you sure you added a custom action?

Thanks Sergey,
I don't understand your comment. Yes I added a custom action : please remember the custom action is correctly executed when I use the line command "msiexec" with parameters : "msiexec /i MyApplication.msi /l*v MyLogFile.txt"

Please see my comment to the question.

Try to follow these instructions:
http://wixtoolset.org/documentation/manual/v3/wixdev/extensions/authoring_custom_actions.html[^].

You code fragment does not show if you did anything else properly, starting from the Step 2 (see the article referenced above).
