Hi Victor. I checked and you are indeed right. No .NET Framework. However, I uninstalled/reinstalled Nokia Video Converter, and I'm still getting the same error message. I think that qualifies as reproducing the bug with a clean install, yes? I'll go ahead and manually install the .NET Framework, although I'm not sure which version I should use. My machine is running Windows XP SP2. I don't know what else is relevant.
