This message usually occurs in conjunction with a damaged Java installation.

You might want to try uninstalling (properly!) all versions of Java. Then manually clean up any remnants at C:\Program Files\Java and or C:\Program Files (x86)\Java. And finally installing a fresh copy of Java. If you have a 64bit OS be sure to get a 64bit version of java.

The problem might be the underscore in your windows user name "Mojo_000".

Try creating another windows user with no unusual characters in the name.

Nope! I have _ in my name and it works fine.
