Before you patch your system, did you try deleting your old LimeWire installation?

If so, which installer did you use? The smaller English installer or the international installer? I find the international installer has a far greater error tolerancy, so your best chance is probably to try first deleting your old LimeWire installation manually (usually located at c:/program files/limewire) and if Windows is still causing trouble when you try to install the English installer, take the bigger international installer.
