All the Generation 4 models and morph packs must be in the same runtime for the initialization to work. So if V4 is installed in her own runtime folder, the morph files must be loaded into the same. As a matter of clarification, it is advisable that no content be placed into Program Files where the Poser installation is placed by default. In Windows OS from Vista and above, UAC will interfere with any addon as a matter of internal security. You will either have erratic behavior or no access to content. The only content should be Python scripts in the core program. All content should be installed into the default, shared folder. On the upgrade, if you didn't select keep your custom preferences during installation, you will get a fresh install with no custom runtimes attached. However, the update will remove legacy content that came with the original Poser 11 install.
