I'm trying to find out why a Windows 2000 machine has the error "The procedure entry point RtlUnhandledExceptionFilter could not be located in the dynamic link library ntdll.dll." As of now, I guess it is related to uxtheme.dll. According to what I have found, uxtheme.dll is for Windows XP and Windows 2003. Is that any application which will install uxtheme.dll onto a Windows 2000 machine?
