Hi, I am making an installshield basic msi project. I made a custom action which will launch an executable installed with the product and the custom action will launch it during uninstall.
I placed it after InstallInitialize and before InstallFinalize actions but how do i ensure that this custom action will always run before the exe file is being removed by the installshield.
You will want to scheduled it before RemoveFiles Action. You will want to change your condition to REMOVE = "ALL" for uninstallation of the product. Otherwise, your custom action will get triggered when an installed feature is deselected for installation during maintenance mode.
