Abstract: A software installation checker is disclosed. A small stub application is put inside a desktop package, and is run at certain points during a software installation. The stub contacts a server and fetches a library which comprises a class with a method. The stub runs the method on the class, passing to the class the information as well as the server. The class unpacks an engine and passes control to the engine. The engine runs a check with tasks received from a collector of the server. Data is uploaded to the server, and can be examined via a web interface.
