Cleaning up after failed uninstalls

It's a job for the Windows Installer CleanUp Utility.

From "An Ethical Perspective on ICT in the Context of the Other" by J. Ola Lindberg and Anders Olofsson, in the Handbook of Researchon Digital InformationTechnologies: Innovations, Methods, and Ethical Issues.

In accordance with Heidegger, human and world is one. This unavoidable participation and presence in the world is understood as conditioned by relational and socially defned aspects of human and world. As Arendt puts it, humans are born into an already existing world of humans, and all individual actions and speech are thereby preceded by a web of human relations. Humans become humans through a process of always being in the world (Bourdieu, 1995) and in accordance the world is understood as social, built on relations and in which the human, through language, embrace joint understandings, and conceptual constructions that decides the world (Gadamer, 1976). This togetherness, or Mit-dasein if speaking with Heidegger, is the world as it is shared with others. It lays the ground for humans to understand both world and others. The understanding humans make of the world is not to be understood as static or unflexible, a world inherited rather than constructed. It is more a question of a dynamic and reciprocal co-construction allowing the world and thereby the humans to be in an always changing and evolving mode. Due to the relational and social conditions that frame the togetherness, change is an open possibility. As these conditions evolve, they leap ahead of things, making the understanding humans may have of themselves and the world dependent upon a being-in-the-world always ahead of itself in an instable way, always potentially becoming something else, something unpredicted.

Interpreting install failures

When BCM Setup installs or uninstalls, it calls the Windows Installer (AKA MSIEXEC) to add or remove MSI files. The actions of MSIEXEC are logged in a file in the %TEMP% folder.

Sometimes the logs contain MSI error codes; just a number with no explanation.

Here's a list of Windows Installer Error Messages, with remarks, to help interpret such error codes.
