Abstract

A method and system for installing software implementations such as applications and COM classes as they are needed from an external source, such as a centralized network store. When a software implementation is needed, the system and method first look to the local system (e.g., registry) for that software implementation, and if found, returns the information such as a local path needed to use the software implementation. If the implementation is not found locally, the present invention dynamically looks to a centralized class store of a network, to locate the needed implementation. When located, the implementation is downloaded and locally installed in a manner that is essentially transparent to the user. Software implementations such as application products may be divided into features and components to improve on-demand installation thereof.

Claims

1. In a computer system in a network, a method comprising, receiving a request corresponding to a software implementation, determining whether the software implementation is locally installed on the computer system, and if not locally installed, managing access to the software implementation by determining from deployment information independent of the request and associated with a policy recipient corresponding to the computer system whether the policy recipient is entitled to install software implementation, and if so, automatically installing the software implementation from a centralized store based on the deployment information.

2. The method of claim 1 wherein determining whether the software implementation is locally installed comprises the step of accessing a database.

3. The method of claim 2 wherein the database comprises a system registry.

4. The method of claim 2 further comprising modifying the database to indicate that the software implementation is installed.
