3.) When using binarycreator using -t option with path to signed installerbase.exe.

binarycreator --online-only -c config/config.xml -p packages -t <path_to_signed_installer_base> installer

4.) Copy it with the name maintenance.exe to repository folder.

copy installerbase.exe repository/maintenance.exe

copy installerbase.exe repository/
