This sort of question is best directed at the [GitHub issues page for MultiBit](https://github.com/jim618/multibit/issues) rather than here. However, since Jim has answered illustrating a general JVM problem then perhaps it should remain open for others to use.

There they suggest it could be something to do with the installed Java Runtime Environment. This is what the installer uses to run.

You could try making sure the Java installation on your machine is 100% by installing the latest version from:
<http://java.com/en/download/index.jsp>

Then try the installer again.
