Error when running addin express msi installer

We are deploying our addin using windows installer (msi). We use addin express designer to generate visual studio installer project. All worked fine. We would like to add another custom action to the msi, that will be executed before installation. For that we added installer class and added a primary output as another custom action after the adxregistrator.exe action.
But as soon as we add it, when executing the resulting msi , the setup process failes with following error:

Error 1001. InstallUtilLib.dll: Unknown error.

First we thought that this could be caused by our custom actions. However if we create new project (not addin express based) , the custom action gets executed and setup finishes.

Any idea how to fix / workaround it ?

Hello Pavel,

I believe the issue is caused by the properties you set on the custom action. I would compare the properties in the two projects.
