I am using wi***b OSR2.1 and I DO NOT have ANY ie in my system. Limewire works just fine. I am using 1.6d right now, but I have downloaded 2.1.3 and will be trying it soon. If it tells me it wants any ie, I'll just not use it! Usually, programs want ie 4, so this may be something else, like Java VM or maybe not even that. What service packs have you installed? wi***b OSR2.1 will take up to service pack 3.
