Question : Is there a way to list multiple installer with different languages

[NathanBnm]

For example with Adobe Reader DC there are five versions of the installer in different languages. See here ftp://ftp.adobe.com/pub/adobe/reader/win/AcrobatDC/2000920063/

currently not, the manifest validation fails when there are more than one version of installer present. same for different architectures, not only language
