There might be another problem, the first step in Rallas' Howto was to use the cmd console to change to the directory that fft2lft was in, in his example it was "cd c:\myprograms\ttf2lff" enter

This changes the cmd prompt to "c:\myprograms\ttf2lff> (be sure lff is using an "L" rather than 1)
Then at this prompt enter ttf2lff.exe....

The only other thing I did was choose "run as administrator" when I opened the CMD console; I have no idea whether this helped or not.
