ABSTRACT:
The apparatus, system, and method facilitates the replacement of software components. New versions of software components and files may be transmitted to a computer system for purposes of updating the existing software components and files on that computer system. Automatic updating systems, as are currently known in the art, may however, create problems in the receiving computer system if the transmitted software components or files are corrupt or are incompatible with the software already installed on the receiving computer. The apparatus includes a data construct that, when appended to a software component or file for transmission through a communications network, facilitates the detection of transmission errors and of system incompatibilities. This construct (trailer) includes compatibility tags for use with a rule engine or other apparatus to guarantee a software component's ability to coexist with other components within the receiving computer system. In addition, multiple hierarchical CRCs (cyclic redundancy checks) are used to verify data integrity.
