Hi Richard,
Win 7 x64 Pro here ( running virtual machine, that is otherwise functioning, in Vmware on a Mac,)
Just tried again with various directories, none with spaces, still getting the 'Unable to create outfile etc etc' that Mesayre is also finding.
A 32 vs 64 bit thing?
Also strange that demo of 1.11 produces output.
1.2 here.
