Eusebiu,
The installer needs to be able to condition itself to either go through the install wizard or immediately start the installation. I'll explain the requirements:
I currently have a config file with key value pairs that will be used to set Installer Properties via custom action. I would like the installer to skip the install wizard if the config file exists within a certain directory, otherwise, proceed the install wizard as normal. Now I can bypass the install wizard dialogs by running the following in powershell:
As a user perspective, I wouldn't want to open the cmd prompt to run a command to accomplish the above task. I would like for the installer to run a custom action to check for that config file. If it exists, immediately start installation, else, run install wizard as normal.
