System.FormatException: Input string was not in a correct format

Ran into this error when running the SharePoint Foundation 2010 configuration wizard

The issue was that a website in IIS had an IPV6 binding. Apparently the team that built the wizard never thought to test on a machine with an IPV6 binding, they also still haven’t released a patch / update for this.

How does something like this get past QA? Seriously.
