This executable should work: https://github.com/sariths/radAux/raw/master/windows/tempCompile/eplus_adduvf.exe .Replacing this executable with the one that already exists on your Radiance/bin directory will suffice. The bin directory that I am referring to is your original installation and not the one that I shared on 24th.
I was able to recreate your error on a couple of other machines, and compiled a new version of the executable after some troubleshooting. I tested the IDF that you posted, and the program seems to be working the way it should (the calculated view factors are towards the end of the idf): https://www.dropbox.com/s/8gmr1htpt8ywuhj/Revised.idf?dl=0

PS: If it still fails, (and you are up for more troubleshooting adventures,) please send me an email at sarith(at)sarith(dot)in.
Now it works, thanks! I´ve replaced the executable on my original bin folder and everything works well.
The Viewfactors are getting written on the idf and look coherent. The problem now comes with EnergyPlus, that doesn´t seem to recognise these view factors and keeps throwing the same error as if they were not there.
I´m investigating why this happens and I´ve opened a thread on unmethours. I´ll keep you posted once I get it solved.
