title: SBT installation error (module not found: org.scala-sbt.ivy#ivy;2.3.0-sbt-2cf13e211b2cb31f0d3b317289dca70eca3362f6)
body: <p>I'm trying to install SBT. I went through few cycles of reinstalling SBT and JAVA, restarting pc and so on. Everything I was able to find in Google about similar issues seems to refer to later stages of using sbt.</p>
  
  <p>I'm a complete newbie, so I might have missed something obvious along the way.</p>
  
  <p>Here's what I do:</p>
  
  <ol>
  <li>I install SBT via msi installer.</li>
  <li><p>I run "sbt" in command prompt.
  This is command prompt window (I manually broke all the links in the same way in order to be able to post this question):</p>
