[SOLVED] Revo wants to do a "New" install on an existing site

How does the Revo install decide whether there’s an existing site? Is there a way I can convince it the site exists?

I’ve encountered this before and it’s always frustrating that the "Upgrade" radio button is grayed out.

As always, it looks for the configuration file that gives it the details for the site.

Thanks. I see how it happened - I was playing around with Shamblett’s idea of deleting core/packages/core and I accidentally deleted the /core directory. I restored it from SVN, but of course config.inc.php didn’t get restored. I’m back in business now.
