Abstract: Retroactive verbose error logging may be provided. Loggable event entries associated with software installation during installation may be saved. Each of the loggable event entries may have a first level or a second level. In addition, the loggable event entries associated with the first level and the second level may be saved to a log file if an error occurs during the software installation. Furthermore, the loggable event entries associated only with the first level may be saved to the log file if a milestone occurs during the software installation and the error has not occurred before the milestone occurs. The software installation may be stopped if the error occurs during the software installation and the software installation may continue if the milestone occurs during the software installation.

Abstract: Described herein are one or more implementations for facilitating the installation and/or maintenance of software products from a cached software-installation source. With at least one implementation, an installation-source manager loads installation-source components of an already-installed software product into an installation-source cache of a computer. The manager then enables the loaded installation-source components in the installation-source cache so that the computer is configured to acquire installation source components of the already-installed product from the loaded installation-source components in the installation-source cache. The manager does these things without re-installing the already-installed software product. With at least one implementation, an enterprise installation-source manager obtains installation-source components of a software product.
