I have the same issue. Vlite is running on Windows XP (32 bit), all SPs installed. I have tried to re-install vlite, after trying to install x64>wimfltr.inf... (as I have a dual core machine and would like Vista to be 64 bit) since it didn't work I re-installed vlite, and then installed x86>wimfltr.inf It didn't work either. BTW, vlite crashes immediately after selecting the Vista version (Vista Business in my case). What is the difference between VistaBusiness and VistaBusinessN? I have tried both but neither works.
