So I've just installed Wamp (2.5) and I want to get a copy of an already existing ZenCart site to work in the wamp server so that changes can be tested there first before being rolled out live.

My ZenCart (1.5.0) versions are:
PHP: 5.3.5
MySQL: 5.1.54
Apache Server (don't know what version from Tool -> Server Info)
Database Patch Level 1.5.0

I've tried a few sources of instruction on how to get it working, and even seem to have successfully installed zencart in a separate directory on wamp (www/zencart/). But when trying to visit the site from Wamp (www/MySite/index.php/) I get the ZenCart message about either not having installed zencart, or having incorrect paths for configure.php files. I tried to make some changes to paths in configure.php according to the guides that I'd found but none of the changes were successful.

Mostly I'm interested in a step by step guide to go from fresh install of Wamp to a running copy of my site in the test environment - if possible. Otherwise point-and-shoot troubleshooting would still be helpful.

I tried to provide clarifying information and explanation of the issue I'm having but if anything more is needed I can provide it so as to best describe what is/is not working.
