My own example from a decade ago: https://sourceforge.net/p/portableapps/launcher/ci/default/t...: you can’t run PortableApps.com apps from the Program Files directory for a few reasons, but for some reason we decided to allow overriding the guard anyway, but in a clear and verbose way: you have to set an environment variable named IPromiseNotToComplainWhenPortableAppsDontWorkRightInProgramFiles to “I understand that this may not work and that I can not ask for help with any of my apps when operating in this fashion.” (case-sensitive).
