Dynamic suite composition is a Microsoft Application Virtualization (App-V) feature that enables applications to be sequenced separately from the plug-ins and middleware applications they rely on, while still being able to utilize the virtual resources such as file system and registry settings, in the virtual environment. The packages will run and interact with one another as if they were all installed locally on a computer. The primary package will also assume the secondary packages entire virtual environment, including the virtual file system. If there is an installer associated with a virtual application package, the installers will be automatically updated. This application is not supported through the official Microsoft Support channels. Please use the Microsoft Application Virtualization TechNet forums to provide feedback or report any problems.
