SEPSetup.exe
I using a batch to exe file converter (must be special not all bat2exe that exist helped me, I used one of f2ko) I created a setup.exe. After this, I created a setup from the export not creating single exe. So, I renamed the setup.exe that the system created by export operation to SEPsetup.exe and I copied the setup script in format of exe file. Then I launch the install using a existing package.
Thank you for your suggestions.
