The comments to this question Excel 2013 32bit and 64bit crashing on form were removed when the asker accepted my answer but the actual answer and quite a few 'Things to try' steps was in the comments on the answer. The answer itself isn't what fixed his issue and now the comments are removed and unavailable to anyone else having this issue. We were prompted to stop commenting and start a chat but neither of us had the needed 50 reputation to do that. It might be an idea to add a link to the archived comments instead of deleting them in case the answer, as in this case isn't the answer but the correct answer is in the comments.
The idea of comments is that they are ephemeral and should not be counted on as a place to write important information. Only use them to ask for clarification.
You will find the comments here, and I would like to ask you to include all the relevant information in the answer itself.
If you think about it from a visitor's perspective, it makes a lot of sense. At Stack Exchange sites we try to remove the noise from the signal, and a chatty comment thread is all but helpful when you're just looking for a quick solution to the problem.
