So, I voted to close the question Locating a dependent hotfix (80451) as has one other person.
After doing so I started to wonder if the better approach would be to rewrite the question as 'How do I locate a specific hotfix for Tridion?' and create an answer basically containing the content of Frank's comment 'You will have to contact Customer Support for this one. It is not a question that the community can answer, just the SDL Tridion folks'
It seems like if the question was re-written as such it would be a good community wiki question.
Does it make more sense to take this approach instead of closing this question?
