A system, method, and program product for accessing or retrieving on a computer network the required software to process a file is disclosed. According to the invention, it is determined, when accessing a file, whether or not software required to process this file is already installed on the user's computing device, depending upon the type of the file. If the required software is not installed on the user's device, the address of a server from which this software can be downloaded or accessed through the network is extracted and decoded from the filename of the accessed file. A browser or file transfer program is launched on the user's computing device and a request for the required software package is sent from the user's computing device to the server corresponding to the decoded address from which it is downloaded or accessed. The software is then unpacked, if necessary, and installed so as to process the accessed file.
