A method and system for aggregating installation scopes within an isolation environment, where the method includes first defining an isolation environment for encompassing an aggregation of installation scopes. Associations are created between a first application and a first installation scope. When the first application requires the presence of a second application within the isolation environment for proper execution, an image of the required second application is mounted onto a second installation scope and an association between the second application and the second installation scope is created. Another association is created between the first installation scope and the second installation scope, and this third association is created within a third installation scope. Each of the first, second, and third installation scopes are stored and the first application is launched into the defined isolation environment.
