Does anyone have an actual document or example on how to customize the 5.0 MSI installation? Is it the same as the 4.6 customizations? Same png sizes? Because I don't see a vpnclient_en.msi in the default package.
The customized installation of 5.0 version of vpn client is same as of version 4.6. The vpn client package contains file "vpnclient_setup.msi" which can be used for installation. Following link may help you
