i have installed the latest wamp 2.0 and it seems to be running well. i am using vista premium.
i can see the two services running - wampapache and wampmysql, both are started
i am also able to get to localhost and phpMyAdmin
the problem is that any php pages that are in the www directory (including the default one) are not displayed correctly, as in the php code is not processed and in firefox, it is just displayed.
