title: R.dll file missing
body: <p>I have installed R(x64) in my system with extra libraries.
  I have setup the path in environment variables for both R as well as Rserve(one of the few extra library that was downloaded)
  No when I open up my command prompt and enter R, it accepts the command but when I enter Rserve to check, it shows "R.dll is missing".
  I have tried reinstalling the R package but the same error pops up every time.</p>
