finding Julia in R

Question

I installed Julia 0.6.0 (release x86_64-w64-mingw32) on my acer 64 bit. Operative system: Windows 7 Home Premium (which is a supported platform). I wanted to use julia via XRJulia. First, I matched R working directory and Julia homedir. See this post

Now, I checked whether R can find Julia:

library(XRJulia)
findJulia(test = TRUE)
[1] FALSE

But it can't. What am I missing?
