Many thanks to Uwe Ligges for his response below. ff for Windows 64 bit?
"No, it does not work and is on the exclude list for Windows 64-bit building on CRAN - hence no binary available. The maintainer has been contacted and has not yet provided a version that works. So you have to fix it yourself and try to convince the maintainer to do so for you." I will contact the ff maintainer.
