ABSTRACT:
A software program running on a computer automatically replaces itself with a newer version in a completely automated fashion, without interruption of its primary function, and in a manner that is completely transparent to the user of the computer. This is achieved by means of a logic module that is incorporated into programs. The logic module performs the functions of locating and identifying other versions of its associated program, determining whether the other versions are older or newer than the currently running version, and replacing older versions of itself with a newer version. As part of this operation, the logic module can copy the newer version to its current location, move the older version to a secondary location, and remove older versions of itself that have been replaced by a newer version. The new version that is to replace an older version can reside on an individual computer, or can be present on a server to which a number of computers are connected via a network. With this arrangement, software upgrades can be effected in an efficient and automatic manner, without resort to any external resources.
