We've actually an issue filed to rename the standalone version as evaluation as that's all it's meant to be as it doesn't use a robust database nor do we want to support the embedded application server that drives it. It's perfect to evaluate the product however if you plan in taking it further (which we hope you do!) I would recommend using the war distribution.
What errors did you see during the installation process of the standalone version? How far did you get in the installation process?
