The definition given for "too localized" begins with:
"This question is unlikely to help any future visitors..."
However, the fact that this question has been viewed over 5,000 times seems to demonstrate that there is at least some interest in it. Also, there's now this comment:
I don't see why this is closed! There are more than a few users of Windows 7 that are interested in using LyX. It's very frustrating to find a question that is exactly on point with a question I have but to see it closed...
I would like to see this question re-opened, since it seems apparent that it is not an issue isolated enough to truly warrant closure as "too localized". If the question is still off-topic however, I would suggest it be migrated to SuperUser.
