Dudes, I have solution for this trouble (for me). Maybe it's helps someone else. FML Installer downloads damaged scala files and JVM cannot open it. Step 1: Run FML Installer. Check %MC FOLDER%/versions - if installer created "1.6.4-Forge-blah-blah" folder, then move to step 2. Step 2: Download these files: http://repo1.maven.org/maven2/org/scala-lang/scala-library/2.10.2/scala-library-2.10.2.jar http://repo1.maven.org/maven2/org/scala-lang/scala-compiler/2.10.2/scala-compiler-2.10.2.jar Step 3: Replace files what been downloaded with FML Installer. It placed at %MINECRAFT FOLDER%/libraries/org/scala-lang/.... This solution works with MagicLauncher.

Emm, sorry... What files you mean? Java applications is multiplatform and can be executed on each OS where installed JRE or isn't? Ha! I did it!!! =) FML was installed with help of mighty console. I just exectuted installer.jar... However, thanks for reply.

This error is actual for me too. I tried to re-download recommended installer, it's strange, but it isn't work again =) I have a clean MC 1.6.4, latest Java 7 Oracle on Linux Ubuntu. It's not fine if we must to download some libraries from other resources, IMHO.
