Exchange 2013 Trial on Windows 2012R2

Hello,

I've downloaded the Exchange 2013 Trial and I'm trying to install it on a 2012R2 Server Standard. It complains that Windows 2012R2 is not supported. Checking the system requirements online, I can see that it is, but only with Exchange 2013 SP1.

I don't seem to be able to find the trial with SP1 - is it available anywhere?

Thanks,

Joao
