Ok I got it working like a charm after installing an older version of OSFMount to C:\Program Files\
HiyaCFW Helper 3.0.2 in combination with OSFMount v2.0.1001 gave no errors whatsoever.
Same problem here. I installed the latest version of OSFMount, ran HiyaCFW Helper as administrator and it puts this error out:
"This script needs OSFMount to run. Please install it."
