This question was just migrated from Stack Overflow to Super User: How do I fix a Delphi installation when "repair" doesn't work?
I know that it concerns installation, but it seems to me to require specific knowledge and expertise that will be much more readily found on Stack Overflow than on Super User. Does that matter? Is the fact that it concerns installation of a product enough to mean that its home is on Super User?
I ask the question so that I will know in future what to do. If the correct home is on Super User then I'll stop answering the questions on SO and then vote to migrate them.
