I've also remove the scala-library-2.10.2.jar and the compiler.
When i run the installer, i get the error «these libraries failed to download. Try again ''org.scala-lang:scala-library:2.10.2, org.scala-lang:scala-compiler:2.10.2''»
I also tried the download again the libraries on the EAQ and put them back, run the installer, i got again the same error message.
Is there any installer who already doesn't need to fetch the libraries on internet ??
