The problem was that the Manifest file was incorectly named as Manifests.
So unzip the Lolo file, rename Manifests as Manifest then re Zip the Content folder, the renamed Manifest file and the Supplement file as IM00069889-01_LoloforGenesis8Female. Now it will install.
Nor renaming the manifest (s) ... I have used the "Content Package Assistant" and everything new. Installed. I think I will uninstall it soon. She has a prudish girl face ... 😀
Thanks.
