It is recommended to install the PowerStore directly on your live server. The instructions included in the read me file will give you the steps for getting things setup.
We have an additional guide on uploading the files to the live server here:
sp_upload_files.php
Once you have the files on the server you can then go through the installation process and begin using your PowerStore. If you would like to modify any of the design parts you can download the css or template file locally to work on it, then upload it back to your server when you are done.
I would not suggest trying to port it from one location to the next without knowing how to go in and update the db or do any db importing or exporting.
