Thanks for the answer but, as I told Sean, I moved on.
I started my journey in the php world six months ago. Once I had configured my machine so that Php, MySql and IIS work together. I started with Wordpress. It worked instantly. Wordpress didn't fit, so I continued my quest. Long story short, I tried Concrete5, Symfony, SilverStripe, Phpixie, CodeIgniter, Kohana, Laravel, amongst others.
Most of them worked instantly. I was up and running with CodeIgniter, Kohana, Laravel literally in 10 minutes, and completed the tutorials in 2 to 4 hours.
It's been 15 days since I posted my need for help, and no one is able to tell me why I can't have the same experience with SilverStripe as with others which run instantly.
I have wasted far too much time with SS than I should have. If it doesn't work immediately, it means it's not well written, not worth it. I don't see why it should be painfull just to make it work. Why would I have to install it on a virtual box when others simply work.
