Abstract: A method for guaranteeing consistency of functional parts across a software installation in a computer that is platform and language independent. Specifically, each software installation will contain a part, for example a DLL that exports a function or variable, which is available to other parts in the installation. All other parts in the installation, for example, executable files and other DLLs, will reference the exported resource. The name of the exported resource should evoke a particular software level and be specific to the software installation it belongs to. All other software installations on the same computer will follow this practice. Thus, all parts in a software installation will effectively reference a software level (via an exported resource). When the multiple parts of software are loaded into computer memory prior to execution of the software, the operating system will attempt to resolve references to the exported resource.
