Provided is a method and mechanism for automating updating of computer programs. Conventionally, computer programs have been distributed on a recording medium for users to install on their computer systems. Each time fixes, additions and new versions for the programs were developed, a new CD or diskette was required to be delivered to users to enable them to install the update. More recently some software has been downloadable across a network, but the effort for users obtaining and installing updates and the effort for software vendors to distribute updates remains undesirable. The invention provides an updater agent which is associated with a computer program and which accesses relevant network locations and automatically downloads and installs any available updates to its associated program if those updates satisfy predefined update criteria of the updater agent. The updater agents are able to communicate with each other and so a first updater agent can request updates to programs which are prerequisites to its associated program.
