How can it be possible? I have exact same version of Windows (updated, LTSB ed.) but none of <= Interlude clients are working. So, maybe fresh L2 installation may solve this problem? If what you're saying is true, there is a good chance to figure out where is the problem, if you are ready to help. We can compare logs of various programs including WinDbg, Dependency Walker and Process Monitor, but first I will try fresh installation of L2 and will check the CFF tool you mentioned.
