Uwe, It is a pity that you decide to maintain your own installer. Although not everyone agrees with my attack to your inclusion of LyxWinInstaller in the trunk, I am pretty sure that nobody likes having two independent windows installers.
Your decision makes me wonder what I would do if I am in your shoes. My answer is that I would either listen to others' opinion and work on the official installer, or fight a better war against a bad guy like Bo. Maintaining an installer without acknowledgements from peer developers is out of the question. There are currently not many differences between the two installers and bundling or not is not a huge deal. I really do not understand why it is so difficult for you to give up some of your ideas. After all, when you decide to work in an open source project like lyx, you already accept an implicit rule: majority rules. Insisting on your own ideas lead to, well, what you have seen. Then, what if you believe you are right, and obviously some users and developers are at your side, but a bad guy named Bo just does not get it? You need to realize that Bo speaks only for himself, and his opinion is as important as yours. What you need to do is try as best as you can to persuade other developers, propose a poll, ask your supporters to speak, show complaints from your users ... I would certainly shut up if you get a majority of the votes to replace the official installer with yours. And in case that you still fail, you will get enough opinions to re-think about your ideas. It is unfortunate that you have chosen a solution that does not do lyx-devel any good. This is certainly not what I was hopping for. Cheers, Bo
