Before you get to see the template to install the BI center site you will have to activate the
PerformancePoint Services Site Collection Features from the :
Site Collection Administration > site collection features
But after i activated it and try to create a site i get correlation error bla bla...
After looking at the ULS log files i saw something related to not being able to use the SharePoint Server Publishing.
So i went to the collection features and activate the
SharePoint Server Publishing Infrastructure
I could create a BI site
